My heart goes out to you, but it seems like he has made up his mind since he said no discussion, just let him go. I'm not sure I believe it that he hasn't found someone else. I'm pretty cynical, though and don't trust men too much. Hasn't been one that I haven't caught lying.

If he hasn't found someone else, then a good dose of his own medicine might work. Tell him "don't let the door hit you in the arse on your way out. Seek a lawyer about spousal support and don't let him see you falling apart!

You will survive and, if you want to, you will find someone else. This is not the total end of the world, although it probably seems like it.

Big hug. Post often, as I think it might help you. oh, and welcome to PC.
