Am I overreacting? Someone please I need advice

Linnea
So me and my SO fight sometimes just like everyone else but when he gets mad at me he just ignores me and says he needs space, so I give him space but then it never gets talked about again after that and if I bring it up or if I try to talk to him while he is mad still then it starts a whole new fight. I am just someone who needs to talk about it, not in great detail but I just want to clear the air I guess. Well now that I am pregnant it's so much worse then before and I am worried I am going to push him right out the door because of my need to want to make up right away. Am I wrong in feeling this way? Should I just let it go?
