So I've been talking to a girl off and on for a while now on the phone / texts and I see her for a few minutes inbetween classes maybe once a week at school, but we never seem to go out and do anything together that would give me a chance at furthering things with her. She flirts a bit, calls me hun, and has specifically said "I want to see you" or "I want to hang out with you" multiple times, but every time I try and arrange something with her she seems to be busy, cancels, or flakes. We were supposed to go out tonight and so when I called her to confirm plans she said "hey sorry I can't go out tonight my mom's friend invited our family over to their house to watch big brother". Sounds like a total garbage ass excuse to me but I wasn't rude about it. Any suggestions?
