Yes you can but it also helps if your girlfriend isn't the jealous type.
No he already has a girl friend
hang out with her more often and then after a few days, ask her to be your girlfriend
i am with another girl friend
yes you can its not i meant anything if she takes it the wrong way just talk to her and tell her what you think. if your girlfriend gets mad you should just talk to her
tell your girlfriend and then go to your boyfriend and say all the good things about your girlfriend
kesha don't have a girlfriend/but her only girlfriend is her friend
You can't make a girl jealous only when you know the girl likes the guy. If you know that the girl likes the guy but already has a girlfriend, then spend more time with the girlfriend that the guy already has and then laugh alot areound her and if the girl you're trying to get jealous treat her like a friend but ignore her, but not too harsh!
girl friend is a friend that is girl and not a best friend and girl friend is best friend
Novia (girlfriend) amiga (for a friend who is a girl)
He has no girlfriend :)
It depends on who your girlfriend is.
I HAVE a girlfriend
