Counselling Teens in (Potentially?) Abusive Relationships

I'm trying to collect some online resources about unhealthy and emotionally abusive relationships. I'm involved in a community forum that seems to have a great deal of teenage girls. I never really took notice before, but ever since they implemented a special topic area for teens, I've been disturbed by the relationships a number of these girls are describing. They are so incredibly desperate and clingy. One, and I'm not exaggerating, went into a panic and blamed herself because she called her boyfriend while he was driving, and the cops started following him. Another, it seems to me, is 6 months away from "he hit me, but I made him so mad and he didn't mean it and he loves me soooo much."

I've found some resources about emotional abuse - symptoms, signs of an abuser, etc. - but while I recognize these characteristics, I'm not sure these girls would. Does anyone have any good resources? Maybe even just on self-esteem, dealing with a cheater, long distance relationships, etc. Preferrably focused on teen relationships.

Thanks in advance!
