Missed my edit timer..anyways..
Edit: I ask because I know exactly what 'position' I'd have taken when my exAgf offered "friendship".. Do I want to have dinner with her(his in your case) cheating/drunk(ing)/shady ass? F NO!...that ain't me! I'd more than likely end getting involved in some nonsense that's non of my concern..There's nothing there with her and I any longer,minus the selfish ******** she thought was going to still happen ..That crap's no longer my problem. simple/solved! The sooner you let go and accept,the sooner you move on and stop living on 'false hope' of whatever fake fairytail you envisioned happening. Not gonna happen,bud.
