How can an unpopular 15-year-old boy ask a girl out specifically a girl he's liked for two years?

Regardless of popularity, this boy should follow his heart. If he desires to ask a girl out he should. Understanding that she may either say yes or no. My suggestion would be that he become her friend and learn what there is to learn about her. With this closeness a relationship may develop. If he justs wants a yes or no then just find sometime alone with her and ask. Start by telling her how you feel about her and why you feel the way you do. Then simply ask her how she feels about you. Being 15 is a very difficult age to build up the courage to ask someone out on a date. You have a lot of influences from friends and so does she. Most girls at that age will do what their friends tell them to do regardless of what she really wants. If the boy asks the girl out on a date and she says no, he has to realize this and move on to a better girl. As you get older you will look back at those situations and thank god for all of your unanswered prayers. If it does work out and she says yes then that is a double bonus. Just remember if the girl says no it's not the end of the world and you will find something better even if it doesn't seem like it at the time. just follow your heart and if it doesnt work out she probably wasn't ment for you anyways and you should find someone who will like you for who you are. yer i aggree just follow ur heart if the girl says no just think when 1 doors closes 2 doors open i lived by that moto and its kept me going so being 15 is like being a baby its only the first bit of life so just do what u thinks best hope this helps xxx
