If there are kids involved, you'd better believe I'd be pulling favors to get some background info, too. Too many stories in the news today about kids suffering and dying at the hands of the "boyfriend."
Didn't say there was hope for a reconciliation; just said he might still care for her.
Most guys tend to be the "surprised" partner in the relationship when it starts to deteriorate.
I was raised in NY at a time when if you wanted a divorce the only possible way to get one was to prove adultery or fly to Las Vegas. Now I guess it’s anything goes. You don’t like him/her? Bye!
My reconciliation comment wasn’t responsive directly to anything you posted, just the reality that IF a couple honestly wants to reconcile, but needs a “time out,” they don’t do it running around with others or investigating.
I would imagine BOR’s ego also is at risk with the idea of her leaving him and going with someone else. She chose a copy, so obviously isn’t after him for his money, esp after 15 years with BOR.
Who knows? Human relationships are complex, delicate things. Marital relationships even more so.
I’m sorry your sister had to go thru that experience. Hopefully by now her life has turned around ad she’s found someone who appreciates her.
