Best Friend concerns...

I'll try to keep this short, although I'm sure I can go on for hours about it.

Now, I know that people change when they go to college, but my best friend of a decade has gone from sweet little Irish girl to Social Liberalist Hippie who sleeps with whatever guy offers. She went to a mini-ivy league school, joined a co-ed frat (though I can't call it a frat around her, to her, its a 'society'), and no longer has a life beyond this place.

Men have especially been her problem. I'll list events so as not to go on forever.
-Started dating Scott first week of college. They took each other's virginity. Happy until summer, when she started having doubts.
-Cheated on Scott with Chuck (who looks exactly like Scott, might I add).
-Broke up with Scott for Chuck.
-Chuck broke up with her a week later.
-Had a fuck buddy (She doesnt like it when I call him a fuck buddy though).
-Had a one night stand. Her excuse for the fuck buddy and one night stand is that she 'didnt want to be afraid of sex'.
-Is currently dating Andrew, who is ten years older than her, doesnt have a car or steady job, met him as an alumni of her 'society' who went back to the campus for a party. He also looks exactly like Scott and Chuck. EXACTLY. And because she doesnt have a life outside of this 'society', she never meets any other guys.

And it seems like she's really holding herself back for this Andrew guy. She originally wanted to study abroad in Ireland; She had the school picked out and everything. Now she wants to take summer classes at the school in his hometown, claiming it will be cheaper. She was going to go into gene-psychology... now she doesnt want to do the work for that and has settled on being a private school teacher. She's going to a mini-ivy league school to be a private school teacher.

I could probably add more, but I'll stop here. I just dont know what to do about her, if anything. Am I getting riled up over nothing? I just cant see my best friend (20 years old now, 19 when they started dating) being happy with this guy she met because he returned to college for a party, who is 29 years old and litters her neck with hickies.

What do you guys think? Anyone go through something like this?

Jam it back in, in the dark.

Well, I haven't done anything, certainly not told her how to live her life. I go to school two hours away from her, and we (unfortunately) never really talk other than vacations. I've taken up what Nadienne said in staying friends with her of course, and use the policy of staying neutral when it comes to this guy.

I guess in my attempt to make a short post so that people would actually read it, I left out a few details.

All of the listed above happened within less than a year. Its not like I never gave this Andrew guy a chance; I met him and his first impression was not the best. I walk into the room and he's pulling up his pants, he basically ignored my "Hi, I'm Ally" and the hand that I put out to shake his, and during the whole conversation he had a 'holier than thou' attitude. And I think the main thing is that I'm being pulled in two different directions, because I also have her mom (my 'second mom') constantly on my case to find out more about how Meg is acting, but at the same time telling me to be her friend. It's wearing me down.

So I guess the question really wasn't 'what should I do about her', its more like 'what should I do to stop this from bugging me without severing the friendship that I've had since 7th grade?'

(And CrowdMaker, sorry about the teacher comment, maybe its not so much the teacher thing as she went from wanting to deal in gene-psychology to very suddenly wanting to be a teacher. And even then, she doesnt want the education degree, she just wants to get her psycology degree and get out of there. Dont get me wrong, I have a supreme respect for teachers, but the way she put it was basically "That's 4 more years of school and too much work, so I'm just gonna be a teacher.")

There's nowhere I can't reach.
