Depression

My boyfriend and I went trying to get pregnant but we were both very excited when we learned I was. I am now 25 weeks and I feel like I'm in a rut. I rarely feel happy anymore, even though I want to be because my baby boy makes me so happy. I feel like my relationship is suffering and I don't know what to do. I don't feel special to my boyfriend anymore and just like I've been put on the back burner... I'm tired of being left out of things just because I'm pregnant.

Anyone have any advice?
