idk what to do anymore

I am currently 13 weeks pregnant. Me and my boyfriend have been dating for almost a year things are not always okay but we work through it. Before getting pregnant we were very sexually intimate, we would have sex almost everyday. Now that I'm pregnant their are days when I just don't feel good or I am just not in the mood 😔 My boyfriend gets so mad telling me that I no longer love him or want to have sex with him. sometimes he even accuses me of seeing someone else. I tried explaining to him that sometimes I just don't feel good or I tell him to give me a minute but I end up falling asleep 😭😔 This is my first baby. Has anyone else been through this? what should I do? TIA ladies.
