Do yourself a favor and find the movie "The War Of The Roses" on a streaming service. As soon as you said: "Not to mention how the marriage counselors pushed me to be more vulnerable and to share my feelings, all of which were weaponized and turned against me by my STBXW." it made me think of that movie. If you've seen it, or when you see it, you will immediately understand what I mean.
P.S. I do not suggest urinating on her fish. (You'll get the reference if and when you see it!)
