Tell her you think you're mature enough to have a girlfriend. If she's still not convinced, SHOW her you're mature. Example: do things without being asked to, like cleaning your room.
1st tell him to stop and then it dosnt matter if you like his girlfriend or not tell her
You cant really do much as you cant control others, you can dump her if it is really bad. Tell her you will report her to the police (if this is physical abuse). You do not need to put up with this. Finish this relationship.
Tell him that it is very impolite. Make him understand that she is your girlfriend and he should stop undressing her with his eyes.
tell him/her you don't want to be their girlfriend/boyfriend! if they don't stop tell them to stop or else you will slap them!
Tell them you have a boyfriend, see if they care about you not having a girlfriend.
Just be on-est sorry i cant spell
If she show's respect to you and is not about having sex.
Well you don't own your girlfriend, as she doesn't own you, you don't really have the "right" to tell her who she can or can't talk to, if you feel like your girlfriend is cheating on you with this guy tell her that, but if she's just talking to him claim down, not a big deal.
make sure that he is flirting with you...and if he really does like you then tell him that you cant go out with him until he breaks up with his girlfriend.
Stick your D in her mouth /problem
If she tells you she's pregnant
