After having a baby

I just had a baby 4 months ago and I swear my SO attitude has completely changed towards me. He has no problem being rude to me or upsetting me and then all I hear later on after I wont talk to him is how sorry he feels he acted like that. I'm starting to feel like it's never going to change the way he comes of to me and he won't see my point of view he just thinks it's stupid. Has anyone else had this problem?
