The basis to make any girl your girlfriend is to first start to know her if you are ready to commit to a relationship with her. As you learn more about her you may develop feelings for her and thus that is when you make your move to ask her out. I advise to do your best in events like asking and taking her out. You want her to know you actually care for her so try to be courteous and surprise her, make it special.
Firstly, You don't MAKE a girl be your girlfriend.. she will choose to be it. Secondly, You just ask her out.
Well if he has a girlfriend and if you are a girl beat up his girlfriend and if you are a guy and you like his girl make out with her.
