Welcome to the board, Justin. There are times where I read stories (again, we are only getting one side of the story, granted) where I just shake my head and wonder what the heck is wrong with some people? I've always found it terrifying the lack of remorse that some people have about their actions and the impact those actions have on others in their lives.
I'm not saying this to completely blame your W for everything that is going on, as there is always 2 in a R/M, but it seems as if your W simply does not care about how her actions impact you. There are 2 confirmed A.
The question, from an outsiders at this point, is why would you want to be M to someone that has no regard for your feelings in this manner? I know that is a rhetorical question as we all have been hurt by our partners in our R/M here. I sometimes wonder how others could forgive their partners for how they treated them, then I read my sitch and realize that it's easy to judge when it's not your own R.
I'm positive that asking her to leave is a start in the right direction. I also think that enforcing that boundary is the key.
I wish you the best!
