---ask if you will express deep remorse and regret repeatedly and pat my back and hold me and make me feel better - she already has. She doesn't need to do it again.
Then why are you experiencing such deep discomfort with XW? It is good to see that she has already expressed remorse and regret. It's hellva more than we've gotten from our WASes let alone mere acknowledgement.
I am wondering if XW is reaching out to you as a means to repair and restore your friendship in her own way. It just seems to me that if she does not do X, Y, Z in the exact same way you EXPECT, then you just throw up your arms and say that's the same ol' XW. Is it fair to her? This has the makings of an ugly dance that she cannot win because you have this expectation that she preform according to your own hidden standards. Why not give her the benefit of doubt and make some allowances along the process?
If I were in her shoes, I'd be pissed big time and may just say, "fvck this...isn't worth my time/effort." And walk away for good. Then you'll never know nor experience the 'new' paradigm between the two of you because you haven't truly given her a chance.
