I agree with Yail, you sound like you have evened out and are taking a pragmatic approach to all of this.
If you felt that you had to try, then you did what was best for you at the time. I know its frustrating, but the only way through is through. Now you know.
This thing with AP has to play out. Yes, it [censored]. But you don't have to be a part of that.
I think it would be best to stay out of WW's head. Detachment is possible - the best way to start is to just start. At first it is very counter to what you would think, but you will get the hang of it.
Remember that detachment is for you. Let WW deal with her chaos. Her actions with AP have shown where she wants to be. Those are her choices. And there will be consequences to those choices later.
Fortunately all you have to do to protect yourself is figure out how to remove yourself from that drama. You don't have to be mean or rude or fight. It is possible to be kind and compassionate and also firm.
