Yikes! A speaker about dating once said, if others break up with you using the line “It’s not you, it’s me.” every single time, then it really is you! And your ficlet proves it. He is telling her that it’s her, not him, even though he’s a jerk for using her.
LoA

JERK ! butshe was stupid for getting involved with him. good story

This is interesting. He sounds like he’s trying hard to be a jerk and that he is intentionallyt trying to break her emotionally.
