So I dated this guy for six and a half months. I really liked him but he started being a really huge jerk about three weeks ago and then he started threatening me and I broke up with him. Then my best friend, let's call her Blah blah, said "Awesome job, bff, I'm so proud of you, I stopped being his friend too because he started being really horrible to me." Two weeks ago it was, "I feel kinda bad, I think I'm going to see how it goes and think about being his friend again." One week ago it was, "We're going roller-skating for New Year's." And yesterday it was, "Is it ok with you if I date him?

So I want to know if I should feel horribly betrayed or what because I yelled at Blah blah a bit, then warned her it wasn't safe, then I gave her permission because I think a little pain will be just what she needs to learn to take relationships seriously. I know that sounds bad but you don't know her-she has so many boy problems because she doesn't think about any of her decisions. She told me that if it turns out to actually bother them she would break up with him because apparently, "Chicks before dicks," but that just kind of made me feel bad for him. His entire relationship was riding on his ex-yeah that'll end well.

So should I be angry and try to sabotage it, or should I stop being Blah blah's friend? Or should I do nothing and be there for her even though I'm not over him and it's breaking me up all over again on the inside?
