I want him to want me again.

My boyfriend and I have been together for 5 years, Dec 30. And for the past year, I've really not been in the mood to get dressed up or put makeup on or do my hair. I dont even wear a bra most of the time, or pants. I gained a lot of weight, well, a lot to me. He doesnt look at me, or talk to me really. And when he does its only what he wants to talk about, and I cant get a word out.

I guess the question is, how do I feel good about myself and capture his attention again? I feel awkward and super self-conscious about my body. I want him to want me again.
