Oh, come on. If a man doesn't want to have sex with you before marriage, he isn't going to want to have sex with you after marriage. I've known two guys who advocated celibacy for religious reasons through college and afterward, and both ultimately acknowledged they were homosexuals. If this guy was a heterosexual, believe me, he would have found a woman to marry. If my wife were still alive, she'd rebut that claim.
I'm so sorry you lost your wife -- my condolences.
