Stop my friend from marrying a girl who is horrible.

My friend, Dillon, has been dating a girl named Mallory off and on for about a year or so. Over this time, she has done many things that has pushed him over the edge to break up with her, but she always guilts him back into dating her. You might be thinking "but pussy too bomb" BUT LET ME TELL YOU THAT IT IS NOT WORTH IT no pussy is that good pussy game ain't that strong. She has emotionally abused him, but he, like many abuse victim, convinces himself that she's worth it. She has stolen his car, forcing him to walk home alone, at night, does drugs with her friends though he asks her not to, has threatened him with calling the police just because she is angry, has PUSHED HIM INTO TRAFFIC, and is generally ungrateful and mean. He is blinded by the booty. Please help.
