When theres a girl that you like, and you feel she might like you, talk to her. Text her, call her, just talk to her. Text her little things during the day. Call/text and tell her good morning. Play with her. Tell her she looked pretty today, and then when she says "Thanks." or "No I didnt lol" or something along the lines of that. Haha. Which they will. Just go back and forth, let her know how you feel about her. Make her feel good when you talk to her, make her laugh when you talk to her, and she will want to talk to you.
