I’m so sorry. Work, go hiking, go hangout with friends, get a new hobby, start a new show, learn different recipes, find new podcasts… occupy yourself. You’re so strong, and you will be okay. It’s okay to hurt, it’s okay to cry. Don’t hold feelings in, it’ll just bottles up and come out later. Let yourself feel how you feel… then, get up and go do something. Find your interests & independence again.
Get a support system, friend, family, coworker… anybody you can call, text, FaceTime during the day to help vent/relieve stress. Who your able to be comfortable with. Sometimes you just need someone to listen to.
Find motivational videos, testimonies of people going through the same thing.
Remind yourself this is & will be painful for a very long time. Their is no time frame of when you will “get over this”. Everyone is different.
Highly recommend podcasts. Podcasts on the topics of dealing with divorce etc. they can give you so much insight on what your going through.
Reach out to anyone who may have gone through a similar thing. Ask for a lunch meet up, maybe once a month, twice a month.
This will take time. Lots of ups and downs, some days better then others. But you have to find healthy outlets. Journaling is major. Going on a walk by yourself in a safe area, by a lake, at the park. Treat yourself, your still a human being. Buy yourself things that lift your mood up, an ice cream, ice coffee, new lipstick, new sweater, new shoes, spend hours at the library, spend hours at a community center, spend hours outside in the fresh air.
If you believe in God, PRAY PRAY PRAY for help through this difficult time.
Seek therapy if you can afford it.
Try to make a new friend with someone is who divorced as well. To share something mutual and have support.
You are not a FAILURE. If you had a genuine heart and it was not reciprocated… it’s hard to understand now, but this is what needed to happen. Your path, your relationship, your life can never be compared to anyone else’s. This is YOUR journey, your life. If you put your all into it… it’s going to take time to accept it and get over the heart break but take your time. 
You don’t. You suffer through it and come out the other side. Go through the stages of grief. It’s normal; you have suffered a loss. If it is interfering with your daily life, get counseling. Maybe join a divorce or grief support group.
Maybe do some rituals to say goodbye to this dream and your relationship with him. Light a candle, release a balloon, say a religious prayer as you would for the dead.
Introduce new joys and habits into your life. Take up a new hobby, take a class in something fun or academic, keep a gratitude journal, make a new friend, meditate, volunteer. Exercise of any kind helps you in many ways. Find something you enjoy;
Stop trying to communicate with him for now. Everything is still too raw. Write a letter with what you want to say. Don’t mail it.
Understand that you are gaining knowledge and resilience by going through this experience and look for the lessons. Know and have confidence that you will triumph and get through the grief and be an even better person down the road. One day you will wake up and most of the hurt will be gone Envision a life where you can
Sadly I’m in the same boat honey only difference is we hadn’t gotten married yet. It’s hard to feel all alone best thing is to have a support system that’ll be your backbone and your strength through it im still hoping we’ll work it out but no luck so far we aren’t even speaking. Keep your head up things will get better is what I keep telling myself even when all I do is cry.
I’d say just move on. If there’s no trying on his part then it’s never going to work. You can’t force him to care.
Take care of your self pamper your self. Some days eat junk and watch TV. Others get out and do something
You will have to grieve the marriage. Therapy and then slowly learn the new you.
It’s hard but it gets easier work on yourself surround yourself with good friends and family and talk about how you feel to them. Try not to follow what he is doing or dwell on why you aren’t together just focus on yourself and making yourself happy and someone else will come along when you’re ready x
