Low self worth

I just turned 40 a few mths ago and am having feelings of low self worth, i have been in a relationship for a long time with an older guy and we don't have kids. I am overweight and he hates that. I've dieted and lost but i always gain it back. We have no sex and sleep in separate beds. I have tried to end our relat. But he won't let me go. I feel so empty and undesired - like I am invisable to men because of the names he calls me. I have certain times when I want to have sex and am to the point where i will not initiate it because he mocks my body. Anybody have any words of wisdom?

A man like that seems to be leeching off what is to be desired of a relationship, and mistreating what is not. I am not foreign to the concept of people being criticized and discriminated for their weight; my sister and friends constantly dwell in such matters; but if he does not appreciate the fruits of a wonderful relationship, albeit it be unconditional love and deep intimacy, or something as glorious as a child, he is simply misguiding and undermining you. Reaping the true essence of a relationship is meant to be mutual and empathetic. He should appreciated you more for what you are worth. If he cannot bear such indemnities, than it simply proves he does not own up to your caliber. You deserve more from a relationship; don't be hesitant, and make the same mistake made by countless others. I am an introvert. I have been that for as long as I can remember; and yet I always felt compelled to strive to be something I'm not; social. Pain and depression were my only companions. And when I realized what I was, and accepted it, I received great revelation. Accept yourself. If you cannot, he cannot. If he regardless does not treat you the way you should be, there is always someone else out there. Do not be afraid to waver unto another relationship; you may just conceive better results.

you can change yourself bit by bit,the first problem is your body changes as i believe you can,and can give advice you to be interested in yoga and the another one is psychologycal you must accept the things in you that you cant change,about diet i can say you must take a diet it will be forever for you because if you one day stop it of course the weight gets back.
