I agree with all the above statements. I'm not sure that he's cheating on you, but his actions certainly don't have anything to do with you-- after all, he's the one that's changed- you haven't. I can see how it would hurt your self-esteem and make you feel rejected when you initiate... My first thoughts go towards anything different in his work environment or in his life outside of your relationship that might be more stressful than usual? Also, have you just talked to him about it? A lot of men don't seem to realize how closely related sex and emotions are, and his past actions with the phone calls make me think that perhaps he just doesn't see things on that level. Perhaps you guys should go and see a counselor, especially since it seems to have really hurt you. Until then, we're all pulling for you and here to listen anytime Best of luck!
