Break up with him for good. If you really have a lot of self esteem, leave him behind. You don't HAVE to try and maintain a relationship with a self-centered, insensitive, completely humanly detached person. Let them go

Seeing other guys while you are married will lead to more problems. I know it may be hard, I truly get that; but get at least a separation before you even think of it.

when ur husband is such a retard then no its not wrong to see other guys

Go for it!! And leave him.

Sounds like he has a shit ton of problems. For something like this, best to have a game plan and a support system of close friends and family(Plan "B"). Don't see anyone else just yet. It could backfire, especially as he comes off as a depressed hothead. You're playing with matches.

Yes. If you feel you need to divorce him, then that's one thing, but as long as he's your husband, he's your husband
