So there’s this guy who can’t make up his mind if he wants to date me or not. He’s not into me but he’s into other girls but it usually doesn’t work out. When it doesn’t work out he decides he finally wants a relationship with me. Whole time in the relationship he’s toxic. He does nothing but flirt with other women and pick on me behind my back. When I breakup with him or I reject him, he makes fun of me to my face and everyone else. Why does he need to date me if he isn’t interested?
