Should I leave or stay?

You should stay and he should leave. Kick him out and make him pay child support. He is an emotional drag on you. Those were terrible things he said to you. Kick him out, change the locks, get child support.

Have you actually talked to him about your feelings?

Sounds like kicking him out isn't going to work, so you might want to leave. Pack up the kids, and spend some time at your parents', or a friend's house. The holidays are kind of good too, because you won't have to worry about your kids going to school.

If he promises to change, give him concrete criteria. He must make dinner every day for a week, or something. If he fails that, leave. Don't go be a whore and then call him back. Take care of your kids and be happy - that's the best revenge. Not that you're vengeful.

I will NEVER understand why girls have babies with dudes who they aren't married to and then are surprised when those dudes bail out. It's not "like" he doesn't want to be with you anymore, it's obvious that he truly DOESN'T. My opinion is you should never have gotten yourself and those innocent children into this position in the first place. Do you have any idea what kind of damage you are doing to them raising them in a household where you and that d-bag argue all the time? You made this bed with your unwise decisions and now you muse lie in it. If you've got the skills to earn a semi-decent wage, then get move out and get on with your life. Obviously he is obligated to pay child support so make sure he does that, but I wouldn't count on him to participate in any other way.

Kick him out and sue him for child support. That ought to teach him not to take a great thing for granted!

Leave or you will be miserable your entire life. Believe that!!! Men dont change.

You have two kids and he goes to school ! WTF, kick him out and tell him to get a job
