So you're gonna blame her?
He lied to her when he pronounced his marriage vows. What was she supposed to do, hire somebody to do a polygraph?
If he had any honor or sense of decency he should have kept his word and stayed with her. Many men--- no matter what their orientation label --- get tempted by the promise of better sexual gratification outside of marriage, be it with a woman, a man, a boy, or just somebody more young and sexy.
The commandment is not "Thou shalt not sin ... unless thou art really, really, tempted."
He should repent and go back to be a better husband to his one-and-only wife, and a better father for his children.
"Gay" is no excuse. It's like any and every adulterer who ever said, "Hey, what could I do? I'm a horn-dog!"
I actually agree with you. But the ex husband in this article doesn't appear to have been cheating on her -- which he could have done -- he simply divorced her. Probably the least-bad thing he could have done.
The reality is that EVERY case of a divorce includes one or both of the spouses determining that the other wasn't the person the thought they were or had changed from the person they were.
