Hunny I think you should talk to him and ask him how he feels about you and about this relationship. It seems like it's a mess why is he even talking to other girls what makes he do that. He doesn't know that you cheated on him so what will be the reason for him to cheat. But the best thing to do is to talk to him and see what he has to say. But the thing is that you guys have a baby and you cants just leave him and go your own way. But seriously you really have to talk to him his not doing the right thing!
