My exgf cheated and left me a year ago for a guy who she had class with. After trying to still be her friend a month after it happened I decided I couldnt do it anymore and went NC. Today she still tries to call, text and even has tried bothering my friends to see where I've been, while she continues an on/off relationship with the other guy. I have never seen another girl act like this and I dont understand why she can't just be happy in her new relationship. Has anyone on here experienced this, is there, anything i should do?
