Okay this is for a friend, please help because she's drivin me insane!!!?

what you just said in your story is what you gotta tell her. let her know why she's not in a relationship and why she's had 7 bad relationships in a row. speak the truth. and the truth will hurt her but let her know you're telling her so that she can have the same chance as you got with your bf alec. and if she gets mad and doesn't listen then you'll know what kind of a best friend she is. and screw that, talk to our boyfriend at night rather then listening to your best friend. i know it sounds mean but you gotta do what you gotta do.
