19 year old guy and 15 year old girl together?

One factor that I believe has something to do with it is that a man starts out a relationship full of great stories that can be told to a wife, about what he's done or who he is. He can recount stories of his friends, descriptions of his travels, tales of his relatives, and can share feelings he's had all those years concerning many subjects. It's pleasant and intimate to go through all this with someone who loves him.

But then the day comes when he's not only gone through all the stories, but also the excitement of his twenties and thirties, the danger, the adventures, the accomplishments, all that is in the past, too. Now he looks at his wife as an old familiar friend who makes life comfortable for him. In a way, she has morphed into his mother rather than his lover.

She wouldn't have liked this comparison, so he doesn't tell her that. Then along comes a young thing who has decided he has something she wants. Maybe she sees him as having money or property or maybe he's a ticket to travel.

Perhaps she's even attracted to old men. She listens with rapt attention to all his stories, and the man gets the feeling that she thinks he's just wonderful. And he's got now thirty or forty years worth of stories to tell her.

When he gets to the adventures he took with his wife, all he has to do is pretend that he did these things alone; it was him alone hiking in the wilderness or sailing to the island. Now I know that sometimes it's not infidelity that ends a marriage, or that it could be the woman instead. But my point is, it's somehow linked to using up the stories.

We've made a persona of our old memories, and we feel that telling these stories to fresh people reinforces our sense of self.

Could be they married young and after 30 years they may still be just starting their 50's and feel they are still young enough to start over. They may feel they missed out on something and with the kids gone they want to see what it was and with less responsibilities this time round. They do not understand that they can't leave the past as there is just too much of it with that person they want to get away from.

They would do better to loosen the ties that bind and not sever those ties. The time will come ( and all to soon) when all that history with the other mate becomes a great comfort rather than an unwanted part of their life. EDIT: abuse is a different thing all together.

But that situation shouldn't be allowed to go on that long either.
