I have been with my fiance for over 3 years now, he proposed to me at new yeears. We haven't slept together for over 6 months, (bar 2 or 3 times when I have questioned our lack of sex life,) and it is ruining our relationship. When I am repeatedly rejected my the man that I am supposed to spend the rest of my life with, it seriously knocks my confidence. I feel undesirable, unsexy, and borderline repulsive. We used to have sex, at least 3 times a week, for the first 2 and a half years, we had a strong relationship, we were the couple people were jealous of. But now I find myself fighting my tears on a daily basis, wondering wether our relationship can be saved. As a result of this I am having severe mood swings, I often dress up to got places, even just going to the shop to get some milk, in the hope that I will get some attention from somebody. I am behaving like a confused teenager and I hate it, it is not me. I have always been faithful and never even considered going with anyone else, but the way I have been recently, I don't know if I trust myself not to cheat if somebody gives me the attention i'm not getting at home, i'm just such a mess.
I have spoken to him about it several times, I have approached it cautiously, explaining how it is making me feel. The most he has ever told me is that he does love me and he does fancy me and find me sexually attractive, and that he just doesn't know why he doesn't want to sleep with me.
I don't believe that he is gay, as he is regularly comments on women, no different to the way he used to. I also trust him completely, I do not believe that he could be having an affair.
When I confronted him, I asked him if he still loves me the way he used to, and the way that I love him, and he says that he does. I am completely out of ideas. Something needs to be done though because I cannot carry on like this.
All advice welcome as I am stumped.
