So there's this guy I like and flirt with. He flirts with me, I flirt back. He only flirts with me to uses it as an ego boost to flirt with other girls and ignore me. And then when it doesn't works out he comes back to flirt with me but only to get some confidence after being rejected. When I don't flirt back when he comes back he gets all pissed and feeling like im lead him on and Im the one doing it for the ego boost.
