There are remarkable parallels now, in h's behavior and his own father's.
Yeah, it's spooky how they repeat the dysfunctional patterns from their own childhood. My ex left our marriage when our kids were just about exactly the same ages as ex and his sibs were when their mom left. Even though just a couple of years earlier he had taken pride in convincing a friend of his t stay in his marriage. It's some crazy subconscious stuff that goes one.
(At first I accidentally typed "sunconscious" - I like that word! I want to be "sunconsious"!)
