You don't tell him. It's too late now.
tell your friend that you like he and if your friends with the (girlfriend) tell her that you like him and if she gets mad DRAMA QUEEN then when they break up you have a chance. :):):)
You don't.
If he has a girlfriend, you should deal with him only as a friend and be respectful of the girlfriend. Once he and she have broken up, then it's appropriate to tell him you're into him.
If you like a guy and he has a girlfriend then you should back off and only try and be his friend.
try to be a great friend of them. then tell them that their is someone in your life that you love him. and at the last tell him i love you.try to be better than his girlfriend. he'll realize he is missing out, and dump her for you
are you sure you want a guy that likes someone other then his girlfriend. lets say the guy and your friend break up and you and the guy get together then another one of your friend comes along and he likes her instead of you. how would you feel? i think you should tell your friend about it.
The best thing to do in this case is to tell your guy friend that you don't like it when he calls constantly. Tell him that you don't always have time to talk and that you don't want to feel like you are on check. Just be honest and things will improve.
tell your girlfriend and then go to your boyfriend and say all the good things about your girlfriend
Ask him about what he thinks your relationship is like to him ask questions like do you think of us as bff's or really good friends but not girlfriend and boyfriend or do you like me more than a friend?
Some friend! To have a friend who want to butt in on your girlfriend is not a friend. Didn't it occur to you that what this friend of your friend did is really lousy? He wants to take you away from his friend! Watch out for this guy! I certainly wouldn't trust him.
If you like him enough, ask him. If you are just interested, get a friend to ask one of his friends if he has one.
Tell yourself nothing will happen between you and think of ways in which you are just friends.
