Should i move on or just have hope? I'm really confused... I don't know wat to do anymore .-.

My ex bf and I broke up… after 3 month we started talking and hanging out again. I still loved him but I also like 2 other guys . We both flirted and did things couples would do , we even made out and stuff. I tell him I love when I do c him but he just smiles or touches my cheek or hair... It kills me that he never says he loves me back . He claims he isn't using me but I just don't know anymore. He calls me his girl but when I ask him if he loves me he goes quiet and doesn't answer or changes the subject . When I ask him if he wants to be together he doesn't know.
