I think that you should give your ex not much information about your relationships because he/she is not dating you anymore so its best if you just tell him/her that you are just having fun with your new guy/girl friend.
If you are in relationship and also love your boyfriend . Then if your ex asks about what you two are talking about. You should not tell him and also tell him not ask this again.
i will answer your question with mine why would you want to know that
absolutely you should go on his facebook right now.
You ask her.
If you want to be mean, join in their conversation. Or, you could just smile at the guy and walk on by.
Friendship begins with conversation. If he enjoys talking to you, he likes you. If he doesn't want to talk to you, he doesn't like you.
That guy her friend is talking with is the son of her friend.
you will know that he likes your friend because he will always bring her up and he will want to be around her.
Chances are he's trying to talk to your guy friend to possibly ask about you, maybe find out things you like.
It means he is into you, but doesn't want you to know.
You hang out a bit you have a laugh you talk a bit they enjoying talking to you and there nice to you but there still your friend if they tease you in a jokey way.
If you have trusted friend that is a boy in the conversation he might tell you if the guy is talking about you or not. Another way to find out is to pretend you are about to do something , for example take a drink of water from a water fountain close to him. These are some ways to see if a guy is talking about you.
He will have trouble looking you in the eye, and trouble talking to you.
