Is this cheating? (Very short explanation)?

I dont know if I would clify it as cheating because they dont hook up or hang out. But it is def. wrong. You shouldnt let him treat you like this or let him get away with it. Even if he is just a flirt I personally wouldnt want my guy talking like that to another girl. If it bothers you and you have asked him to stop and he really hasn't I would say goodbye to him. You dont need that.
