My husband changed after 14 years of marriage. For 14 yrs he was loving, affectionate, wanted me all the time, had great sense of humor and took care of himself, his appearance. Now he's cold, uncaring, has no emotions, never wants sex anymore and lucky if he showers once a week! It's been like this for 10 years now and I'm at my wit's end as to what to do? He refuses to talk about it and the few times he has he just says he doesn't know why he changed? Any advice would be great!
