He means exactly what he says. What else is happening in yoru life, apart from what you have just told him?
It depends. Does he mean what else is going on in your life at the moment? Does he mean what else is going on today? Does he just sound like he has nothing else to say? There's no real context to judge this on.
say sure. You don't have to mean it
she wants to know if your going to break up with her or if your just happy
Yes, that's pretty much exactly what it means.
he likes you
This means that everything isn't going right with your boyfriend. Why else would you feel like this if everything WAS going right.
He is asking you out. Reply as appropriate.
It means he likes you and he wants you.
Hes interested =) He Likes Youu
it means he had already asked this question to someone else n had got a better reply... so may be it means he is cheating on you... ;)
It is very plain what that your ex boyfriend is asking you if you are seeing someone else. Since he bothered to ask you it is possible he may still be interested in you and perhaps continue another relationship with you.
It could mean that, or if you're close to her it could mean she trusts you.
