Okay so here is the situation, I have been with this guy for a year and a half now and I love him madly. However his sexual libido hasn't been as high as mine. He hardly ever initiates anything, and when we are doing stuff he seems very distracted. I have been asking him if something is wrong, he says that he's tired. Well, recently I was really fed up and I pressed him against the wall and made him tell me the real reason. He was in tears and said that he felt so bad, but he goes "I'm used to being with thinner girls, maybe if you were thinner I would initiate sex more"
My heart sank. But keep in mind people, I have been this weight since I was 17 (I'm 23 now). I was never the skinniest girl in the world, I am 5'6 and weigh 140lbs. I have curves in the right places and I have always LOVED myself.
What I don't understand is, why did he pick me in the first place? If I wasn't his preference, why date me? It's not like I gained 30 pounds while we were dating! I just don't understand... I feel so ashamed now.. all those days where I would parade around in my underwear, I felt like a queen... little did I know he was probably thinking what a disgusting beast I am. :(
I also know that he loves me, and he is overwhelmed with guilt that he feels this way. But why would he want me to change somethig that he chose?

Your weight is not the issue, if it was, it would have been when you first meet. You pushed him and he attacked you back. He has another issue but wants to blame you, instead of addressing his issue.

Never change for him, tell him to get counseling to deal with his feelings.

A lot more going on than he is saying and my bet has nothing to do with your weight,

Don't take his issues to heart, its HIS problem to overcome, not YOURS!! Maybe the thing to do is instead of letting him hurt your confidence, and self esteem, kick him to the curb to wake him up.

I think you are fine as cat hair the way you are and he is making up BS excuses to justify his attitude, or lack of a good attitude. TRUST ME, after a year and a half, something else is going on so don't be distracted by your own hurt feelings. Find out the FACTS, and don't be blinded by feelings, his, or YOURS!!

His libido is not as high as yours and this can cause an undo stress to perform. Confronting him was an additional pressure that he took badly, and right or wrong, you have to change your approach to this to bring him in, not push him out. This isn't about sex, its about your very different approaches to it. Its surely NOT about your weight, I just don't buy that, and neither should you.

Honey, you don't need to change yourself for anybody. 140 lbs is fat? Even if you lost a lot of weight for him and got really thin what would he want you to change next? YOur hair? The way you dress? I would tell him if he doesn't accept your body than he needs to be with somebody who is thin. A lot of men like women with curves. Look at Marilyn Monroe for example. She wasn't 100 lbs and men loved and adored her body.

Start running, and I don't say to support him being such an @$$hole about it, but running will keep you healthy. However, I am only recommending this because obviously he has a six pack and has no faults in his body, if not, then maybe you should consider whether he really loves you for you and not for your body, but still keep up with your shape, but for YOURSELF.

The guy is an a$$. To tell you something like that after he has been with you for all this time is inexcusable. I agree completely with Fr_Chuck and everything he said. There are other issues at work here and your weight is most likely not one of them.

If he didn't like your weight, he wouldn't have been going out with you to begin with.

The worst part of all of this, aside from the obvious, is that now you will be completely self conscious about your weight because of what he said. Let me tell you right now, there is no reason to be. Don't let it get to you in that way.
