So I had sex with this girl from my social circle... big mistake.

I want to have nothing to do with her, but she has been showing clingy behavior, passive aggression and manipulation to get me to pay attention to her.

i has got to a point where she sent me a text today about how she was at a party and some swingers were invited and that this one guy made her cry.... I don't know what to make of it.. ithink this is an attention seeking behavior and I did not want to engage.. but how do I get out of this, do I tell her anything or should I just stonewall? It will be a little awkward to stonewall entoirely as I do see her at events.

Thanks
