Thanks for posting on my thread. I think I just need to talk to someone.
Just a couple of comments but nothing that already hasn't been said.
I too would feel some satisfaction at XH's R with OW withering and dying. I think that's only human. I bet you also get some satisfaction in being viewed STILL as competition from OW. That is pretty pathetic that she is that insecure, though. I'm sure she was spouting off out loud fully knowing and intending for her words to get back to you. She is displaying her guilt and insecurity by saying those things but displaying false bravado when she "announces" to you (so to speak) that she will win him back, so you better not get any funnny ideas about him and trying to "win" him back yourself.
I also agree with everyone regarding your XH not wanting the end of the R to get out to you. I think alot of X's stick in that ugly OP R because as a sense of pride they don't want to admit it failed, even if it is not going well. Especially when they gave up and destroyed so much to have that R. He might also think you that you would say "I told you so" (deservedly). I bet you are the last person on earth that would do that and maybe deep down he knows that too. This only further elevates you to Saint status...something he in his mind could never measure up to.
