Okay. later that evening when we were all home he showed mom and I the pictures. He had apparently seen LB and I but didn't say hi. Instead he took distance shots of us standing in line. Creepy?
Maybe. Is there some context that you're leaving out? He may just not have approached you because there is tension or because he knew you were doing a thing with LB. I have been a weirdo before and avoided saying hi to people I know exactly because I'm a weirdo. (Now I try to say hello.)
On #3, my last post from last week is similar. A long time ago I resigned myself to a deep understanding that my XAH was a liar who lies. He lied to me, to authorities, to therapists, to his parents, the police, the judge, and a lawyer. He lied to my family, my kids, employers, friends, other family, etc. Liars lie. I am no longer shocked and disappointed at the depth and breadth of the lies. I'll never know the extent of them, but I know he lied in abundance. And so it goes.
