I meet a guy it was out of the blue , and kinda just happen it started out as just friends because I am married (but very unhappy) over the phone and e-mail we talked I new him in grade school but it had be a very long time . He was sweet and undestanding about everything he new I was going through areal hard time , he would e-mail me poems and cards and sweet little notes and really had me feeling special which is what I had been missing I really liked him and felt he was a good friend , then all of a sudden it started to change he started asking me about personal things about myself , and sexual things and I have to admit it was kinda exciting to me , but as time went on it became only about sex and he wanted me to go into detail about my sex fantasies and things like that , when I would talk to him he would be sweet then turn the conversation to sex in some way all of the cards stopped and so did the poems he says he wants to spend the rest of his life with me ,that he has always loved me . He knows it will be a while before anything can happen between us as far as a relationship more then friends and says he will wait forever, I kinda get the feeling that I am some kinda obsession with him and am not sure what to feel about him , I know he is as lonely as I have been , but I don't understand the change from being friendly and sweet to being all about sex . Also when I ask him if he would like to go out as friends to lunch or to a movie he says he can't because we would have to have sex with me if he was around me . help I am not understanding this .
