i think it is possible. or he might do it as a joke
Yes he does, obvoiusly man this is basic stuff.
it could be that he still has feelings 4 them and is upset or sad that she broke it off with him or that he broke it off with her
Yes if you fall down stares it is very likely.Out of a window still likely it depends what part of your body takes the plunder. Stay out of windows and careful when using stares.
It could mean somany things, may be he is not yet ready for that or he still wants to know you more.
It means you're still in middle school.
That meant he could not stand being without you.
he is happy
He'd rather be with you.
He likes you.
Could be because she still has some feelings.
he's a horny pervert who can only think about getting into your pants;)
If your ex Boy friend stares at you then he might still like you or he is just being silly. Boys normally do it when they want you back. I would be cautious. This guy is fickle and would treat you no better the next time; he'd aways have his eye out for his next best bet.
