Good to hear you're moving on and enjoying yourself, sorry to hear about the mixed signals from XW but that's to be expected. My W has an old saying- she doesn't want you but she doesn't want anyone else to have you either. I'd view what she did as spew and not read anything into it regarding reconciliation. That's a silly notion that it's your "job" to pursue her, like you said when you tried it she ran, so now you what, didn't try hard enough? Bottom line is she still wants to blame you. Just keep up with your detachment!
