After he cheats again and again

Well I wouldn't give him the chance to cheat over and over again (atleast I hope that I wouldn't put myself in that situation).After he cheated on me the first time, it would be over and I wouldn't even want to speak to him again (unless we had kids, I would talk with him only to make visiting arrangements.).

Well don't hit that is violence. But if the relationship is not good for the family no divorce him. It is not good on a child to be around constant conflicts and stress as I guess there would be there. Perhaps even councelling may help you make your mind up.

I personally would kick him to the curb. No one deserves to be cheated on once let alone again and again. No man will ever disrespect me and my child that way. Get rid of him. He doesn't deserve you or your loyalty.

Better leave him for good. Better in you rplace there is divorce and maybe start a new life again than spending the rest of your life with a cheater.
