I was in the process of giving feedback regarding your post #2357174 and had to stop myself.
If we are going by the premise that your W is MLC, and I think she is... then you really have to come to terms that no comm is safe with your W.
I'm not saying go dark. I'm saying that no comm is safe with your W. And you really have to do something that I think is truly your life lesson in this sitch. D E T A C H your emotions from her actions and words...
Have comm with her, but she WILL spew. Even on the most benign, rational, logical comm.
But you are attached to comm with her (we're going back to your co-D and ACOA stuff, here) and you are likely seeking validation where there will be none.
I get that this is hard for you, and I understand.
You just need to move forward and detach and leave the sitch to God.
You need now to be true to you. The BEST PON you can be. There is nothing you can do that will be "right" or that will "fix". You know that.
