would he like it done to him
just leave him alone...let him flirt ,,as long as he doesn't break them up its ok
well if she doesn't like him then it probably not a problem but if the boyfriend finds out then he should stop it's not the best sitution when fists end up on a face
exactly. say if you had a gf would you like a guy to hit on her constantly?
tell him that it's not right, because she's already in a relationship, and that if he would have to wait until it's over to be able to do that.

Tell him to make a GF! probably he is looking for one or alone.
Tell him that's its wrong to flirt with somebody else's girl. Ask him how would he feel if that was his girl and another dude would flirt with her.
Tell him that his heart will be broken if he does.



and it is wrong



slap him if you want
It's fine. Don't worry about it. He could flirt if he wants to. No big deal. Fix your grammer a bit. :P
No it is not okay.....it is over stepping boundaries...and disrespectful to the other persons relationship and significant other. Would the person in the relationship like it if the tables were turned? It creates trust issues within a relationship.
Stop the flirting because if the girl's boyfriend finds out, he might get it a big fight with your best friend (guy). Or he might stick a knife in his tire on the car, or maybe he breaks his nose and puts him in the hospital.



Tell your best friend that's a dangerous thing to do. Or show him my answer.
as long as he does not have a girl friend
