Well, it seems he is not only angry with me and blaming me, but mostly at her for going along, ignoring his needs, etc. It seems he is furious to the point where she feels he despises her.
I've never actually seen a cycle of love-bombing, devaluation and discard. I know that I only have part of the picture, and that I am by no means neutral, maybe wishing for this to be true on a certain level, but this looks very much like that cycle to me. Only as a TikTok version.
The really bad thing is that, when I am hurt and feel discarded/unseen, I sometimes write angry messages, too. Regardless of the fact that I do not feel that way and repeatedly tried to communicate that, these messages sometimes give her the impression that I have a very bad image of her. This is a failure of mine, in some way exacerbated by some of her (for want of a better word) issues. Apparently, his tirades remind her of those messages. So instead of being angry, she now doubts herself, because "we" might be right.
Bloody hell.
Well, I think I found the thing I need to work on most urgently once I find a therapist.
