Do you know any good songs to get over a guy?

theres this guy, were only friends with benifits(his choice). he sends me constant mixed signals and i never know how he really feels, and thats a big problem because that means i dont know how he really feels about me. he knows that i really really like him. he treats me like im actualy special to him one second, then the next second he's all over another chick. i know i can do better but im stuck on this guy. know any good songs to help me ; get over him, forget about him or just make me feel a little more empowered?
