Not in R, just for context. Maybe some day. WW had multiple APs so I have quite a few of these "brain teasers."
My personal favorite was finding out that I was referred to as the "dog walker/dog sitter." Not just by WW and APs, but some of her COWs and friends.
It stung. It's so personal. I put effort into making sure our dogs are fed well, walked, groomed, healthy, and happy. I ALWAYS made sure to be available to take care of them when she would do double shifts and graveyards. Not to mention that they kept me company when my ww was "absent." And I got made fun of for it. Behind my back.
She will never understand how hurtful that was. I swear its like making fun of someone for loving their children. Ruthless.
The only thing that's helped me with that has been time. I was sad, then angry, and now feel pity towards her for thinking that way. I will never feel bad about loving my dogs and if she or people around her really think that's something to be made fun of, F them. I assume some form of acceptance will come with more time, but there was no amount of apologizing that was going to fix that.
There was general complaining about me being controlling, or rigid, or whatever. I've accepted that while there are elements of truth, the narrative is really a justification for the As.
I'm working on being a better person and potential partner, but there will be no R as long as she holds to the narrative that I'm some bad guy. Nope.
And I can say for sure that shit is just a way for potential APs to say "oh you don't deserve that" or "I'd treat you better" or whatever. It's a set up. My WW knew the guys she'd pursued were lame and so she helped them with hints by offering up shit like this. Personally, I'd have more interesting things to talk about. If they have nothing better to say, F them.
Another gem, and this is really the opposite, but a brain bender nonetheless: She told one of her APs that I (me, not him) had fucked her brains out for 2 days. This guy couldn't even get hard without the pill. WTF? I feel for anyone who had to hear the AP was good in bed, I really do, but this really messed with me. It's taken me months to see this as ultimate proof that she was (is?) just living on a different planet. Truth. If I was doing that, and he was doing his thing, and she still went to him... This had NOTHING to do with me.
Another that hurts me in my bones is the AP she never remembered to mention anything about me. He didn't know she was in a relationship, I'm 99% sure. No matter how many times she pulls the "I wasn't thinking about you" card, this is brutal. It's so cold and calculated and callous. And I consider this a version of negative talk, although indirect. If you're shooting for R, I don't see any way around this other than accepting its who they are and what they are capable of and allowing time for them to show it can't happen again. I firmly believe that's either a leave or they are responsible for helping you heal it wound. Not sure you can process that without out help if staying.
There's more. But anyways...
Processing for me, in the context of possible R, is confusing. I can't say what I need, but I can say for sure what I can't/won't do without:
Full admission(I know you mentioned her including negative talk in the TL). If I bring one of these up and get an I don't remember, or I don't know why, or a flat denial... No deal. I left a cheater before without truths, and while I don't want to say it was easy, the processing without truth and without them in my life ended up just being "this was a bad person." If I'm going to stay/R I can't do that.
Processing for me also means dealing with the triggers/movies the negative thoughts bring up. This is complicated and worthy of a separate thread.
Processing for me also means justice. Balancing the scales. And balancing the scales doesn't mean I go down to the level she did, it means she has to come up to the level I'm at. Again, that's in the context of R. Walking away, which I'm not suggesting, removes some or most of that. Staying requires much more work.
I feel your pain. Some days I'm floored that she ever had anything bad to say about me. After everything I've done for her and everything we've been through. Fuck it hurts.
Cheers
