An Update

In the bit of time that I got to spend with Dad, he told me more about what's going on with Karen. He says that he was happy with how things had been going (even though I always heard from Karen that he was unhappy and frustrated), and he wants to spend his life with Karen. She wants to remain married, but live in separate houses. He feels like this arrangement will just mean a lifetime of loneliness for him.

Dad is so hurt that she chose to do this while he was away. And it turns out that she hasn't actually left yet - she moved her things out (and took many things that were originally his too), but she (and her clothes) stayed. Presumably she's waiting until she gets a place of her own to move to, but Dad says that things around their place are the same as they always have been, except for the missing possessions and discussions of dividing the money. She greets him with a kiss everyday when she gets home from work. She even met him at the airport with a hug and a kiss, like nothing happened.

Can she have all she wants? Was he really as happy as he thinks he was? What is the best here?
