Surely your sister knew you loved him. I wouldn’t have much to do with a sister like that. If you don’t want to go then don’t but know your family dynamics.

Many years ago when I lived in Jhb…I met a lovely couple at church, we became friends…this couple used to live with the lady’s sister…the sister and I also became friends and she told me that she used to be engaged…she went away on a work trip and when she came back her fiance told her…that he is in love with her sister! Imagine how awkward that is …all 3 of them were living together. So as much as this sounds far fetched. .it’s does happen!
In my family we had sisters marry brothers one of them divorced and then remarried another sister… if they are in love your will have too find a way too deal with it…
Ewww no! She’s disgusting

It depends. If my sister ended up with one of my exes from like my teen years, 1st love or something, it would be strange, a bit odd, & creepy, kinda gross… But I would still be respectful and I wouldn’t hold a grudge, I wouldn’t be best friends though. Now if she got with my kids dad or partner, someone more recent that I cared for deeply, then ya, I probably wouldn’t go.

If you don’t wanna go then don’t. But obviously yall weren’t meant to be together. Instead of being bitter, you could be happy for them…and if you’re still hung up on your ex, even though he’s clearly moved on and is happy, then stay home.

Your body shouldn’t even react a certain way towards people that have dated a sibling. That’s automatically gross to me.
Don’t go to that wedding. How he can be with one sister, and then have sex with the other and still sleep at night is all she should need to see what kind of man she’s marrying.
Guess she likes sloppy seconds

How long were you together for?
Wow…did she even talk to you about getting with him before they got together?!!
Have you been active in your sister’s kids lives?
If so…I would go to the wedding… for the kids. And I would act like them getting married didn’t bother Me at all. I would say something like, " Idk how you put up with him sis but Congrats!!! Im Glad that we are both better off now than we were before."
But girl… your sister does suck for getting with your ex and I’m sorry about that. But screw it…he’s your EX for a reason.
So they fell in love. And have two children. Maybe you should accept that he is over you!!!
And yes I would go to the wedding. She is your sister. And that must have been quite some time ago
That he went with you.
Move on.
And as to going to the wedding. She has been with him and I don’t believe if you went out together you just weren’t meant for each other!!!
Go find some one who will be in love with you

Get over it! If he is your EX it was for a reason. Although the sister part strikes a cord your sister started a family with him and will have to deal with whatever shortcomings troubled your previous relationship with him moving forward.
Focus on yourself and finding your own happiness instead of dwelling in the past TRUST ME the right person will come along in time.
Don’t go to the wedding instead plan a mini getaway the weekend of the wedding

I need more info, was this like your ex from when you were a teen and now they’re in their 30s and reconnected, did they cheat together, etc. do you intend to never have a relationship with your niece/nephews. Maybe just accept that this person wasn’t it for you and move on. If you don’t want to go to the wedding Bc you don’t support the family they’ve made together then don’t go. This ex did not love you I know that’s hard to hear Bc you maybe loved them. You weren’t each other’s person and they were and I get that it sucks Bc you wanted SO to be yours but that’s not how it played out. If you’re struggling at accepting this and moving forward I’d get with a therapist. Don’t let this affect you long term.

To the people saying just move on I think she is over him. From what the post says it seems likes she is hurt by her sister and that is why she does not want to go to the wedding. I can understand that. She can still be upset and hurt by her sister without still being in love with her ex.

You have every right to feel the way you do.
It’s okay to not want to go.
It’s okay to feel upset and disrespected. But it’s alos something you should bring up to your sister if you feel comfortable to talk about it…
Let people know when they have hurt you. Don’t carry that type of guilt. Express how you feel…

Why do you care who she married? Do you have any children with him? I’m confused. Are they married or are they getting married?

It can’t be both.

It depends how old you were when you dated him. If it was older I’d be heartbroken but if you were a teenager together with him for a few months it’s a little overdramatic
Wait, they have two kids together but then getting married is where you can’t handle it?
Move on with your life. Don’t go to the wedding if you don’t want to, but for your own sake, you really need to move on. They have kids together and are getting married. Clearly there is something for your sister and your ex, that wasn’t there when you were dating. But if you had an issue with it, you should have said something when they first got together, it’s a bit late now.
Do you really want to lose a sister and your nieces/nephews over someone you are probably more in love with the idea of than the actual person?

It feels so tricky!
Like I feel as though your sister betrayed you in doing that. Blood is thicker than water and she should have stuck by you. Like it’s one thing taking sides after a break up, but creating a new life with them while your sister is hurting. I dont know.
I guess maybe the next time you are at a family get together, only eat half your sandwich and see if she wants that too?
In all honesty though,
Focus on your own wellbeing. Put that first. If this situation hurts you, then you might need to cut out the toxic people.

If you don’t want to go then don’t go. If it’s not going to be good for you then you need to choose yourself first. Doesn’t matter that it’s family, people do far too much for their family just because they’re related, sorry but if they’re toxic or in anyway make you not feel comfortable etc then being related doesn’t mean shit.

Ok so this depends… Was this a long term (years) boyfriend or a short relationship that lasted a couple months? How long between you and your sister. Clearly they have a couple kids so it’s been at least a year or two since they started together. Seems weird that you would be upset still. But like I said it depends. Not enough information.
Edit*** Some people clearly can’t read. The question asked if she should go to the wedding. Not if what the sister did was shitty. If my sister ends up marrying the guy I dated in middle school for a month… I’m not gonna give a shit. But if it’s the guy I lived with for 3 years and then they got together, no I wouldn’t go. Like I said it depends.

This is actually interesting…
Before any of my siblings and I were born, my mom dated someone and they ended up breaking up. Shortly after her sister, (my aunt) started dating him and they ended up getting married and having children of their own. My mom was totally fine with it. I know not all situations are the same, but unless you still having feelings for this man maybe that’s why you are so upset about it still. Though it is too late, this is something you should of spoken with your sister in the first place!

My best friend got with my ex and had a kid. It took a few years but got over it and renewed our friendship. Sometimes people aren’t meant to be together and that’s ok. If we hadn’t broken up, I wouldn’t have been blessed with the kids I have now. Everything comes in time. Go to the wedding…be proud of your sister for finding the love of her life, so that she will be there when you find the love of yours.

Unless I knew that I couldn’t keep my emotions under control & be happy for them, I’d stay away rather than be an embarrassment. How

So she’s had two kids already to him and now his kids are your nephew and niece and you can’t change that. He will be in your life regardless because he is the father of her kids. Unless he is a dead beat dad. Anyway I’d be wondering why you are still upset? Are you still in love with him?
If you can’t be happy and supportive, I don’t think you should go. Despite it being such a shitty situation you know?
But I think maybe seeing a counselor or someone and talk through your emotions may help you to move on and find yourself, better your life.
I do understand this situation isn’t easy but I guess you have to decide when enough is enough and move forward rather than history letting you hold you back from something better

I never understood this thinking… why you mad at your sister? Love isn’t about what you can HAVE. It didn’t work out between you and your ex. If you still love him, love him as the new brother in law! Be supportive because YOU love your sister and him and this is bringing their family together and they are happy! The worst you could do is cutt off the people you love over a jealousy tick.
You will get you a man some day and have a wonderful life of your own… but no one wants to be with someone who is still mad at their sis/friend for taking an ex that they are no longer in a romantic relationship with. They will feel second best. Love unconditionally
