tell her how responsible you are
To let your boyfrien come to you, I will convince him to be with you. Example, giving him a nice background about you.
If the girl in question likes you then you won't need to convince her to let you be her boyfriend, you must wait for the signs to see if you think she is interested, let the girl make the move, don't be pushy, be patient.
Prove to them that you're mature enough for a relationship.
Well, if you know that she has a boyfriend that's great. But never let your parents know. Let your sister tell them. Talk with your sister and convince her to tell your parents.
ask politely
don't try and convince her, just let her choose, because really its her decision and its really low to try and talk down about her bf and she might take it personal
well you ask them then you have them meet your boyfriend but make sure your boyfriendd acts how your parents would want your boyfriend to be like

Just wait till you are 16. You can try to convince your mom or dad to let you by showing them that you are responsible.
You may not be able to convince her of anything if she is in "love" with this person. You may just have to let her go and be responsible for her own choices in her life. It is hard to let them go, but you can be there for her IF she needs you.
You cant. if your a minor its unsafe (and i believe also illegal) to do this. you could have one or both of them go with you to visit him.
Buy him a sports car :)
