jbroken, a little bit of my own sitch here to perhaps give some peace. Mine blocked me on FB the moment he moved out and changed it so even basic stuff like where he lived and worked could only be seen by his friends. His OW had already blocked me and my daughter. This was in Oct. At a later date he blocked my daughter and then eventually refriended her. She would tell me about his kooky posts (even when I asked her not to). A few weeks ago my D says that the OW has now unblocked her. I panic, I tell myself that this is because they are getting serious and she is now envisioning herself as my D's stepmom (amazing the stories we can construct for ourselves). I check and see she also unblocked me (I've never met the woman or said or done anything about her. I think she was finally just done with him and was not concerned I would do anything to her). I keep checking every week or so. About 2 weeks later my H suddenly unblocks me. Then a week later I notice that his profile is now 100% public for the first time ever. It has remained that way for the last month or so. Point, these people are nuts. Ignore it and as Sunmoon says, be grateful you don't have to see her with another man (mine never posts pics of himself or mentions other people).

I may differ from some here, but I would never communicate with anyone but my very closest friends and family (those I lean for support) about him or anything he has done. I think it is disrespectful and violative (even if she is doing it). I plan to take the high road to the bitter end and beyond. You do not need to get your "story" out there. People believe what they are told. Then, over time they start to notice the discrepancies in those stories. Far better for them to put together that her stories don't add up than for you to say it. They will just think less of you for doing it. Let the word get back that you are kind and decent and polite, and letting go. Let her wonder why you aren't losing it and spewing (you seem like an emotional guy and she may be expecting that, so give her something other than what she expects).

Stop worrying about who is on whose side, what X or Y believes. All that matters is what you know and believe. Focus your battles on you and your peace of mind.
