You've been hanging out with a group of new friends, but one girl in particular has caught your eye. You laugh at the same jokes, like the same music and have similar tastes in movies. When you're with your friends, the two of you seem drawn to each other, but there's one thing that concerns you. You don't know if she has a boyfriend, and you'd like to ask her out. If she's involved with someone, you don't want to get in the way of their relationship or make it awkward within the group, but you do want to get to know her better and maybe take things to the next level. Do this without ruining your new friendship or feeling like a fool. Keep your cool, be confident and find out if she has a boyfriend.
Direct the conversation to another dating couple you both know. Talk about good they get along, how lucky they are to have each other and how well he treats her. Then say something like, "I bet your boyfriend treats you like a princess." This gives her the opportunity to say she doesn't have a boyfriend, or tell you she does. Either way, you've done nothing to change your relationship and you've found out if she's involved with another guy.
Ask her if she's got a boyfriend. If she answers "no" then ask her out. If she says "yes" tell her he's a lucky guy and you'd be a fool for not asking.
Tell one of your friends to ask one of her friends if the girl has a boyfriend. Her friend won't lie and might give her opinion about the relationship or the possibility of one with you.
Ask her out on a date. If she has a boyfriend she'll likely tell you and decline the date.
