Advice for dealing with a jerk?

Lauryn • High School girl with a whole lotta questions

What advice can I give my friend if she really likes this boy but he just wants her for sex and nothing more? she tried talking to him once and he said he didn't want nothing to do with her but if she wants to do sexual things with him, he will be willing to do that. She won't stop blaming herself and she's thinking about giving him what he wants.
