one thing about the WAWs, and i dont mean to say anything negative about your friend, is their version of what happened and how they felt seems to always change.
so while now she says she wishes he would have fought harder, then it may have pushed her away. and maybe he was fighting, but she wouldnt let herself see it.
there is a lot of self-justification in their thinking, making lists of how you're wrong, evil, bad, smelly, boring, pushy, cheap, etc etc etc.
one thing that is true, is that for the most part, anything you do for her will be received as wrong and will be held against you.
my x complained i never bought her flowers so i bought her flowers and it was pushy. she complained i never bought her cards so i sent her cards and it was forced. you get the picture.
you can fix everything they said is wrong with you and they'll come up with new problems. eventually they'll find something impossible for you and you're in the same place you started.
at this point, its a crapshoot, your W may want space or may want you to pursue. you'll never know, she'll never tell. but DB says not to.
