A good thing to do to get a girl to like you is to play hard to get. Don't be over anxious, don't be a stalker, don't swoon all over her, and don't give her your undivided attention. Girls like a little bit of mystery. Be friendly, be nice, but take it very very slowly. This is important because you don't know if she is going to like you back. You can ask around to see if she has a boyfriend but be very careful because you don't want it to get back to her that you are interested in her. If you want to know for sure if she likes you take it real slow and just be friends for a long time. Friendly conversations will get you a lot of information. You'll find out if she has a boyfriend. If she doesn't give you the time of day you'll know to move on. If she responds and maybe gives you some information that she doesn't tell everyone then you'll know you have a chance with her. It may not be right away but eventually it will happen. Being friends is the best way to start. After a few months if she has responded to your friendship you can ask her out. Most great relationships start with friendship. Just take it slow and see how it goes.
