I appreciate the insight. I really do get this, and I feel sorry that anyone would go through it, not just my partner.
Forgive me for saying so, but what you described sounds a lot like "you reach a point where you just can't fake it any more." Am I supposed to accept that my wife simply can no longer pretend to tolerate me? Have I been "the enemy" all along?
This reply is on the short list for support and validation. I just wish I could get her to understand it this way.
I've heard couple's counseling suggested a few times, but the last time I was finally able to get her to agree to go she said she felt attacked and ended up storming out without finishing the session, and that was before she underwent all this.
Just the other day I confronted her about being interrupted again before I could finish explaining my idea and that I was hurt because she had promised to work on doing that less. She said she interrupts me because my ideas are stupid, as if that validates her active. I told her that I thought she might've had a different opinion if I'd been able to fully explain my reasons but she cut me off again and insisted she'd firm enough information to judge me as wrong by the first half sentence I uttered. I told her that wasn't even my point: that she'd promised to do that less, and I ended up sleeping on the couch.
I don't know how to get through to her and she refuses to try counseling, asserting that she has no issues to work on.
