From Nice To Mean

I need advice. Not sure if this is the correct group to talk or post in anything helps. Well I recently found out I'm pregnant. I have a boyfriend, but lately I feel like he's gotten mean. I understand with pregnancy brings hormones. But he says mean things to me and doesn't apologize, he fusses at me when I'm trying to explain how I feel about things, he even argues more with me. All of this makes me cry and stress, because I'm trying to figure out is it me or is it him?? Ladies any advice? Any words?
