Need more from hubby but feel selfish...

So, my husband travels for work and he is working on his MBA. His travel schedule is finally slowing down, but he still has a lot of work for his classes. I am 37 weeks and have really been feeling it lately. It's more difficult to do everything, I'm always uncomfortable or in pain, and I'm exhausted. We have a two year old also. Last night I asked my husband to give our son a bath be it's hard for me to kneel down and lean over the tub and he acted like I was asking him to cut off his arm. I ended up still giving the bath. Also, Monday was my birthday and he stayed home from work. He asked me what I wanted for dinner. When I got home from work he hadn't done anything around the house, he didn't get me anything for my birthday, and he didn't make dinner (what was the point of asking me???). I feel like I can't bring any of this up, but I need more from him right now. I feel selfish and whiney, but I'm in tears a lot of the time bc this end of pregnancy stuff is hard!!!!
