lol this question is so weird...are you sure whoever this guy is, is attracted to her physically? because that can be a big factor that the guy will have to work out, but you really cant make your self physically attracted to someone. Sexual intimacy adds a whole new dimension to the level and I don't know about the guy and people out there, but I think it is extremely important to be attracted on all levels to whoever you are with.
The whole point of feeling that feeling over a special person, is because that person is special, in all levels
So, no the relationship will eventual fail if there is no growth..and im surpised the woman hasn't left yet, usually when the man is the less sexual one, the woman wants ti all the time. I just can only see 2 individuals being together without sexual intimacy for stupid ulterior motives...like trying to please everyone else
Also...are you this guy is straight? Being dealing with sexuality these days hits all ages, ESPECIALLY anyone in their older years
