You are right, I am choosing to believe her that there is not an affair. If there is, it will come to light eventually, but I've accused her enough of one and she's denied it enough that I can't keep going down that cheese-less tunnel.

She told me today that she intends to make her move to their home permanent, they told her she can stay with them. She said it is because I got angry with her over their behavior last night (which was what seemed to be inappropriate touching), but I think she was already planning this. I'm just going to continue getting my own life and going as dark as possible.
