Husband overreacting?

Jessica
Let me start off saying my husband has been so amazing since we found out I was pregnant. He will usually cook dinner after work so I can take a nap. We both work 9 hour days, so after waking up at 5 and working all day, I'm exhausted. He feels like he's giving me everything, but he doesn't get anything in return (sex). I understand he has needs, but if I'm feeling sick or about to fall asleep, im not in the mood. I really haven't been in the mood much since getting pregnant (I'm 12w5d) and I'll admit we aren't doing it as much as he'd like (he would be fine with everyday lol). I still do most of te dishes and pack him fruit for his lunch every morning and do sweet little things, but I guess I still don't care. He told me that he feels like a paycheck to take care of me and baby (when he/she comes) and now that I got what I wanted (a baby) I don't care about him or need him anymore. He wouldn't kiss me goodnight or even talk to me this morning. I feel terrible and there isn't anything I can say or so to help the situation. Some people don't have sex at all during pregnancy so I told him at least he is getting some. Lol is he overreacting, or am I just being a terrible wife?
