Self Esteem

I love my husband more than words can describe, but lately it seems like we are drifting apart. I don't know why, but I know Its killing my self esteem. Sexy time is like a fond memory, and I opened facebook today to be slapped in the face with pictures of his ex gf who is at least 80 times hotter and thinner than me. She also happens to be the first girl he ever slept with. Then to top it all off, the last week he has been over at the neighbors until like 2 am at least 3 times. I trust him, and I know he is faithful, but it KILLS me that I am second best to a game of cards and facebook pictures. All I can think is that if I were thinner he would want me again, or if I was more fit I could distract him with some crazy new move that would make me more interesting than a game of cards. I'm completely distraught. UGGGGGGGGGGG!
