You would have to tell your friend the truth, and tell her what you have been through with this guy, and what he did to you.
i dont think you want to watch your friend getting hurt like you did.
even tho it will hurt her in the begging but it wont hurt her as much as when he will hurt her!
Just take your step and tell her.
and be very honest with her!
I think in the End she will thank you so much!
