Oh gosh. I'm so very sorry.

Bless your heart, you certainly don't need this. What reason does he give for wanting a divorce? Does he still want to "swing?" With everything you have to cope with now as far as health issues, I think that's pretty shallow of him. Evidently, he doesn't remember the vows he took, huh?
And now you are dealing with serious issues with your daughter, and he's going to leave that all to YOU?? What is the matter with him? Does he have no sense of responsibility or any parental caring or love? He's really LOST it, hasn't he!
Dearheart, you definitely have MY support. You're going to need it.

I just can't imagine what you're going thru right now. But if that's the kind of "man" he is, then perhaps you're better off without him.
I have to say tho that I've heard of this happening many times with people who "swing." Maybe that kind of open marriage isn't a very good idea? It seems that often it comes to this end.

I'm sorry your marriage did too. Please stay here and keep posting -- and if you want to talk, feel FREE to private message me ANY TIME. I'm usually around.

God bless and please take care. Hugs, Lee
