My husband and I have been fighting ( I have believed for some time that he has been cheating on me). During this time, our sex life has been fine, A month and a half ago, we stopped having sex. He says he has no desire, never gets erections through the night or in the morning and 1 time we did try and he got limp. He now says he wants to work on our relationship and I am trying to be supportive, but what does this mean. Is he completely out of love with me? He says he doesn't feel the same that he used to.
