Yammy, great to hear those stories. A golfing friend of my late husband was very comfortably off. In his forties, he suddenly left his wife and children for a girl in her 20s - typical mid life crisis.
His former (huge) home was sold and the ex wife got maintenance, child support - and a very decent 5 bed home with pool. He had a similar house with his new wife - and they had a couple of children.
Fast forward ten years, in his mid fifties, his still young and glamourous wife left him for her personal trainer (also young). Again, the house was sold, everything divided, funds for the children - and he ended up quite cash-strapped living in a one bed flat. She did to him exactly what he'd done to his first wife, dumped him for a newer model!
