It's just something she's going to have to sort through on her own, sadly :( The best you can do is keep doing what you've been doing. Let her know she will always have a friend who is supportive, loving, understanding and always has a shoulder available. The worst is when you start thinking you are truely and utterly alone, so make sure she knows how much you care and that you're always going to be there for her. Think of it like a child who has moved out...they're an adult now, and need to live their own life...you no longer have control of their choices but you can sure be there to help pick up the pieces when they need it, congratulate them when something goes good/right in their life and support them no matter what choices they make - even if (and sometimes especially if) you don't agree with some of the choices they have made.

I know that's not much help, especially coming from someone as young as me But I hope it helped at least a little bit

All of this has been very helpful, from everyone. I really appreciate it. Nice to know we are like one big family who can talk about anything. I can't even talk about this stuff with my own family.

Just keep being her friend. There really is nothing you can do.
She has to want to do it herself. Sad as it is- hopefully she will see the light on this someday! She will really need your friendship- when she gets to that point!

I knew someone like that. Hard to understand how someone can use someone so much.
I'll say some prayers for her to be free of this situation...

Thanks MsTeddy, it is greatly appreciated
