I'm sorry to hear that Liza.
It just shows you the kind of person you were with really is. I would simply be happy you are not with someone who would do something like that to you, it's a blessing in disguise for sure.
As for the Facebook thing, I'm not sure what kind of stuff she is posting, but I wouldn't worry about it. Life goes on, and it's only Facebook.
Thanks for the perspective, glad I left that life behind me...coke and heroin is pure evil. As evil as the people I still for some reason still text with.
Time to finally turn everything around and walk away.
