Oh dear. Lots and lots of reason hun. They range from "he's just too shy to actually call you" to, "he's not that into you". And with guys, it's hard to tell unless you ask them point blank: "Hey, are you into me or not?" Which can be a realllllly tough thing to do so most people will send their friends to go ask for them in a roundabout way. Which works too as long as things aren't getting telephoned oddly (this means only pick a trusted friend who is very accurate at relaying stories for the mission).
We don't know. Everyone is different. Some guesses might be:
The only way you'll know is by asking him.
it means he likes you and wants you to be his boo. Other words his girlfriends
he likes you
hes bisexual
your ugly and frigid.
It means that he thinks your cute but wants to be friends.
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 .
yes totaly
Probably.
He has an interest in you and hopes you like him back.
Not necessarily. But I guess it depends.
Yes
He probably got his feelings back for her
