Not really sure how to go about this

[toodles]

I have a major problem in my relationship. I have NO sex drive. none at all. and I really, honestly think it is because I am just not attracted to my husband anymore. and it has been like this for a very very long time. we only have sex because HE wants to and I just live through it. it has been about a month since the last time we were intimate...and I finally broke down and gave into him last night. but I really was miserable the whole time. I hate that I am like this...but I really can't help it. I am just not turned on by him..and overall, not attracted to him. He has gained about 50 lbs in the last 2 years and he gains it in very unattractive ways. he has as big of a belly as I do at 6 months pregnant, he has as big of boobs as I do...and his neck has rolls. I know this sounds extremely mean...I would never say these things to him..but I do want to talk to him about his weight problem. he knows he has a problem because he only has 2 pairs of pants he can wear...barely wear....and he refuses to buy new ones because he "wants to lose weight." well..he does NOTHING to lose the weight. nothing at all. he eats anything and everything that is in sight. he doesn't walk, or do any consistent exercise at all.

but..I feel like I have no right to say anything to him because I'm not exactly fit myself. I am nowhere near as out of shape as he is...and a lot of my size is my belly...but before I got pregnant, I was about 15 lbs heavier than when we got married.

for Christmas, we bought an eliptical machine that we both swore on using. I haven't been using it because it really makes me very uncomfortable to do it. But I know he has no excuse. Let me also add, when we met, he used to walk his dog 3 miles EVERY day..rain or shine...no matter what. the minute he walked in the door from work, he would change his clothes and head out for a walk. he hasn't done that since we got together and claims he just doesn't have time. I'm sorry..but he has plenty of time. He has just gotten lazy.

anyway...any suggestions as to how I can talk to him about this? It is really affecting our relationship because I have no desire to be intimate with him. I don't even have a desire to cuddle with him. I wish I did...but I just don't.
