Rant husband

So I'm 25 weeks and I'm starting to fall into a deep depression. My husband seams to be very distant. This is our 3rd pregnancy 3rd baby girl. I've tried to put the moves on him on so many occasions and it's always some excuse. He doesn't even seem to look at me the same. Don't call me beautiful or sexy anyone..... Lastnight I wanted him to come take a shower with me before he had to go to work and instead he did the dishes to waste the 30 mins we had together. I'm heart broken. How do I get out of this funk. We have only had sex one time since I found out I was pregnant.
