I need advice..

Okay guys so my S.O. and I are expecting. We’ve been together for four years and we’ve been through a lot and have had all the bumps in the road and disagreements. But I’m kind of at a road block.. My S.O hasn’t really been reading up on any of the articles with me that pop up every week about what all is going on inside my body and what I may be experiencing. But he has gone to the extent of saying I’ve been grumpier since I got pregnant. He doesn’t get why I am a little more snappy or why I have a bit of an attitude. (being I’m tired all the time and mood swings are in full force) He’s asked me if I want to have the baby and if I want to have it with him, because I cry a lot more now when I see videos of babies and their families. (My hormones are a whirlwind right now) it’s starting to affect our relationship because I can’t seem to explain it to him and he feels like it’s him that is the problem. I feel like he’s not really understanding what is going on inside of my body and how it does affect me and my everyday life. So I’m asking if y’all could please drop some good websites for dads-to-be to read about pregnancy, the changes, what to expect. Articles, websites, even book suggestions will help. Thanks I realllllly appreciate it 💖
