First year problems??

My husband and I have been married just over a year I'm desperate for a baby and have stopped contraception for 2 years now. Recently it seems like we never have sex like  never ever. I'm desperate for a baby but don't want to only have sex to conceive but obviously if it never happens then I never will get pregnant. When I bring it up it just causes arguments, it was my birthday and anniversary recently and we went out for dates where I really tried to make an effort to be attractive for him but he didn't even notice. He didn't even try any physical contact and when we got home and went to bed he just rolled over and went straight to sleep. Now I'm left feeling ugly, unwanted and like uk never get the chance to have a baby. What can I do :(
