Thank you everyone. I am such a mess today. Had another contact with this woman, more information came forward, she has been confronting her h. and after denying lots of things, eventually acknowledges some of them. My w. emails me saying something about how this only began a couple of months after the relationship ended and only this fall has it become "serious". She insists this is true and that the contact woman is "crazy", lying, etc.
Then she sent me another email saying I'm obviously on a "witchhunt" with this ow and that if I want to get my facts straight, we could do so in a couple session. It was very aggressively worded. I think she sent this because the w. was phoning her husband like crazy this morning, confronting him repeatedly on things.
So, I've received a phone call with credible information about this affair / relationship / whatever, but now I'm the bad guy??
Even if her version is true (and there are mountains of circumstantial evidence to point to a PA now--and evidence of lots of lying / omissions)--that still means that apparently 8-10 weeks after ending an 8 year relationship, she was already on with someone new.
I feel so replaceable / invisible.
I have extricated from the situation with this other woman (his W.), I know all I need to or want to know. She can go after him if she wants to, that's her business. Any more for me will just hurt further and I have enough of that for now. For the first time, I am looking at what my W. says and thinking there are so many lies here. And no doubt they are working out the "story" version to stick to. That she is still lying to me now even though the story is "out" is upsetting to me.
