I'm in college and I'm seeing this very sweet girl, that's unfortunately (for both herself and for me) hooked on the sorority life of excessive drinking, partying and even drug abuse. I have only known her for a short period of time, so our relationship is not that serious yet, but I would like it to be if she could straighten herself out. She has self-esteem issues and it seems like she is constantly afraid of being rejected because of her issues. So she has a history of resorting to casual sex and rejecting commitment preemptively just to avoid the risk of being dumped first. She finds a life without alcohol and drugs appealing (she hates drinking), but she's afraid of what's going to happen with her relationship with her sorority friends if she abandons even parts of this destructive lifestyle. She also seems a lot more comfortable expressing attachment when she is drunk, but gets really reluctant whenever we speak of commitment.
Should I intervene? If so, how!? Should I leave her and let her figure it out herself?
oh and she has some daddy issues (I THINK the daddy might be absent) and I think she feels like her mother is not really proud of who she is and her accomplishments..
