We know perfectly well why men sniff after young girls, but why do young girls get involved with much older men?
Our brains don't fully mature until mid twenties. The girl is still in late adolescent stage. We have a LOT of students near us and their behaviour and mindsets are definitely not adult. But they are all so beautiful. Bodies and skin not yet changed from childbearing and time. Experience not yet opening eyes to reality.
(So sad that so many of us don't realise or believe we were exquisite then, until years later and we see the photos.)
From when I was about twelve to uni age or so the posters my friends had on their walls were young pop stars. Mine were Starsky and Hutch, Alias Smith and Jones, Captain Kirk, Han Solo. All in their mid thirties. So the attraction is something I understand ( tho never actually got involved with ).
An older man paying her attention will be very different from the boys her age she knows. He'll seem sophisticated - and very attractive. And an adoring teen will make him feel younger, more attractive, less responsibility.
But the consequences, the reality of actually getting involved with a man at that stage and destroying a family?
It's possible she didn't even know about his family. Possible. They do lie ...
For him, maybe he's realised the huge change he's brought on himself.
From respected family man, status, nice home, wife & two lovely kids, domestic and financial life sorted, plus sexy secret bit on the side ...
To being the bad guy, the one who chucked it all away, living in his parents spare bedroom, being financially responsible for a home, life and kids he doesn't get to enjoy, and sexy secret bit on the side starts to represent losing all that and ... Somehow ... She and his wife are the ones responsible for it all going horribly wrong. The mental gymnastics can be quite something. Maybe he's already a bit fed up with teen-ness. Maybe she says 'like' every few words.
For her, hearing he's left his family for her has maybe caused a reaction.
Maybe her parents have intervened. Maybe his have.
Maybe her dad's 'had a word with him'. Maybe she's thought about having someone's dad trailing round after her at a loose end.
Realised she'll have to interact with two children who'll loathe her.
Suddenly not so attractive and exciting after all.
I'm worried op hasn't been back and I'm afraid she's going to forgive and take him back.
But she won't forget. It will always be there, like a stain. After the initial relief, a wary watchfulness, suspicion, and will probably be thrown in his face with every argument.

OP. If you are thinking of letting it go and having him back (his parents WILL be relieved), brushing it under the carpet and forgetting it ever happened will be very unwise.
Remember what you said in your first post about how horrible he'd been to you for quite a while?
Therapy and counselling at the very least.
