he likes you
It could mean Lots of things, in my opinion, I think the guy has a strong friendship with you but might want to be more than friends.
hes bisexual
It means that he thinks your cute but wants to be friends.
your ugly and frigid.
It's a guy thing. They don't wanna seem desperate. Irritating you is his way of saying "I'm madly in love with you, but I don't want you or anybody else to know"
when a guy flirts with you then stops either means hes playing with you, he wants you to flirt now or he liked you then he found another person who is flirting back .
well he may not be flirting with you that's just the way some guys are sometimes and you may not understand it
yes totaly
He has an interest in you and hopes you like him back.
Probably.
Not necessarily. But I guess it depends.
He probably got his feelings back for her
