Makes perfect sense. Thats something that some of us eventually begin to see, that we dont want people like that in out lives. It is sad, but its her choice.
Sad girl is totally right about your options if she is NOT having an A. The whole point of this, not matter what is going on with her, is for you to heal and cope and learn to be a better H. Where she is at the end of all of that remains to be seen.
The whole thing about cake eating is that she has you, who fulfills her needs for support, and consistency, and she has these other misadventures to fulfill her needs for adventure and loser-dom apparently. You would be letting her cake eat if you let her have an A, or act like a 21 year old with no kids, and continue to support and fund it.
We disagree on exposure of A's a lot on here, personally, I exposed my H's, and I wouldnt change a thing. I am pro exposure, if she is doing something that she cant be honest about, maybe she shouldnt be doing it. But really, thats not a decision that you have to make right this second.
I guess I gave the wrong finger to the wrong man...
