My crush kissed someone else right in front of me?

[Anonymous]

It hurt like a bitch. He was saying goodbye to this girl and he told her to give him a kiss. They aren't even dating. Can people really just platonically kiss like that? This happened a while ago but I can't get over it. I don't know if he knows I like him but apparently he likes me. Why would he kiss her if he likes me though? If the time comes should I tell him that I was hurt by it? I don't kiss other guys in front of him but I kinda want to now to make him jealous. This may sound immature so what should I do?

One time my crush kissed someone in front of me after we kissed the previous day. My feeeels! T_T

Then one time this girl asked me if i liked her and asked if i wanted to be her boyfriend, then she avoids me and i see her holding hands with another guy. Afterward, like a month later, she tried to talk to me but i never spoke to her again. She was too heartless.

He likes/liked you but what are you doing about it except sitting around watching him? He is not going to wait around for you, and the immature option (making him jealous) is not going to do you any favours.

Likewise, he's a crush. He doesn't owe you anything, he is not under any obligation to not kiss any girl he damn well pleases.

Then he's not worth it. He is a 1 = A player 2= He isn't interested 3= He doesn't know you like him 4= He did it to get a reaction. Either way I would kick him to the crib and find someone worth your time
