Basically, I (24) love her (17) but she loves him.

Except that he (30) is way to old for her and has a kid - and she knows that he will only hurt her. again... (He also fucked a 14yr old when he was 24 and dated a 14yr old when he was 28, but I am working on burning him for that...)

Anyway, my advice has been to cut all ties - ignore and destroy everything that reminds her of him. (I'm stuggling to get over her, but when when the girl who tells you she wants to marry you fucks someone else less than a month later...well it helps ease the pain in an ironic sort of way.)

What else can she do?

(And how do I get the cops to take me seriously without implicating the girls or myself?)
