S--sorry you are so sad today. He hasn't contacted you yet even to get the papers.
You say he loves OW and cares for her. If he cares so much why weren't they together at his family Christmas? He may not being paying the vet bill because it reminds him of a painful experience. I know that doesn't make it ok, but it might explain it. Why do you continue to torture yourself imagining what they are doing and what she looks like (you say you know she is attractive--how do you know that?) How do you know he loves her, cares for her, he won't reconcile cuz that would make him look foolish, and what he has with OW is totally different than what you had. You kinda have a little drama going on in your own head, and you know they hate it when we decide we know what they are thinking! This stinkin thinkin is bringing you down. I see some of the advice you are giving to others and it's good--take some of it yourself. Be patient--get a life as if he isn't coming back. Just go ahead and take another walk through WalMart and see how many guys notice you. It will give you a little boost! But make note of all the great things about you yourself and keep reminding yourself. No matter what happens, you will come out of this better than ever.
