Why has he gone off sex?

I have been dating a lovely man for the past year and I am very much in love with him. He is in his mid-30s, is very successful and in a high-powered job which he loves. He has had several relationships but has never married. When we first got together, he was really interested in sex and was a good lover, but in the past few months he has become less and less interested. Several weeks can pass without us making love. I am worried that he might be getting bored with me. He said that his last two relationships ended because his girlfriends were unfaithful. One of my close friends said I should end the relationship but another said I should give him more time to see what happens. What do you think? As his last two girlfriends have been unfaithful, he may now have difficulty trusting women. So when he sees the relationship is becoming more serious, he panics and backs off because he is afraid of being hurt again. Alternatively, it might be that he has commitment issues. Commitment-phobic men are good at sweeping women off their feet and making them feel loved and desired – but once these men see that more is expected of them they get cold feet. Some men with this problem begin to lose interest in sex with their partner because they want to move on to someone new. Some will turn to affairs, others do their own kind of relationship sabotage (such as making love less and less) so that eventually the woman they are with decides to end the relationship or is unfaithful herself. Many men who have commitment issues would like to overcome this but others are more interested in sex with a variety of women and don’t want to commit to long-term relationships. I recommend counselling with Relate (relate.org.uk) to see if this can be resolved. If he is willing to come to counselling with you it is a good sign; if not it might be time to move on.
