I am very confused at this point in time with this girl. she flirted with me and showed interest and i pursued that. I asked her out to a movie twice and she said she was busy twice. We dont see each other everyday because we dont go to the same school but we have streaks and talk on snapchat. A couple days ago she sent me a black screen with a heart two days in a row. The second day i responded also with a heart and she didnt respond directly to it except just sending me duck face selfie. Is she playing hard to get or is she actually not interested? How should I advance and move foward with this? ?
