Divorce advice , I am very unhappy

So I am wanting a divorce but not sure how to tell my husband. We have been married for almost 5 years. I am not happy at all. We fight about kids all the time, our last fight I told him I couldn’t do this amymore, he then took off and said he was going to kill himself. I also filed for a divorce 2 years ago but backed out because he said everything would be better if we just stayed together. It was better for about 3 months. Since then we constantly fight about kids (he had one before we were together age 9 now, i had one before we were together age 7 now and we have a 4 year old together) and my job. The fights usually consist of every thing being my 7 year old fault, such as there’s a hole in the wall it was the 7 year olds fault but noone witnessed it. He told my 7 year old that he was not his dad. His 9 year old cries all the time about everything an example is half a glass of water instead of a full glass of water he will throw a fit worse than my 4 year old. The 9 year old will also pee the bed and laugh about it and my husband doesn’t find anything wrong with this. My 7 and 4 year old are both potty trained and do not do this… I am very unhappy but not sure if I should get a divorce or stick it out in fear of him committing suicide…

You can’t stay for someone else. He shouldn’t have said what he said, that is very manipulative. If you think he will harm himself, please report it to authorities.

I agree you can’t stay just Bc he’s trying to manipulate you into it. It sounds extremely toxic and you have to think about your kids more than anything. You need to leave and then report him and call in wellness check on him if you have to.
