is there any possibility that you were out and about the past week or so and did something you can't remember?
Honestly, I don't go back and read my threads and I want to believe that my stbx was never quite off the wall, like that.
I can tell you that I'm thinking how I would feel if my stbx HAD said something like that, and it brings up the same feelings that I remember, while I was going through the "worst" of it and not appropriately detached.
That feeling of "am I...? really...? is it possible? was I really such a bad guy...? I feel horrible that she feels that way..." kind of stuff.
There's that surreal... cognitive dissonance that follows those type of... "encounters"...
Yeah, I'd strongly recommend not responding in any way to that. At best, she's baiting you... at worst... well, I think you want to steer WAAAAYYY clear of her, at this time.
You COULD be nutz... what do I know? I've never met you...
Work on yourself and get to a place where you understand that you ARE (most likely) a great guy who can have a great future, no matter how it looks.
