I wouldn't think that your W has seen the light just yet. That was a testing the waters type of thing. She probably meant it when she said it, but also knows it will get back to you and wants to see how you will react...so don't. For right now, just do you.
The week of drinking, mourning, crying, its good to get it our of your system. Now its time to get back to working out and the positive things you were doing before this latest set back to help your PMA.
Like I said before, you don't have to do anything today. Just let it alone for a while and then when you are in a better place, decide with a clear head and open heart what you want to do. If its to file, then do it. If its not, then don't. Once the anger fades and the emotions are no longer running high, is the time to make decisions.
What rock show did you go to?
