It has happened multiple times now, and I'm quite fed up of the face that I'm apparently constantly doing something wrong. Hope you guys got any tips/tricks. An example of a few days ago: I sent a snapchat of my fully loaded lecture room, where I was sitting in the back, so I had a good overview of my fellow students. I sent the snap to my whole list, including some girl that somehow had made it in my list. I knew her face, never had a real convo with her, only helped her stand up once when she fell off her bike during winter, a year ago while I was still in high school. She now replied to my snapchat and we started a convo, number close --> boom. Fast forward a few days: she doesn't seem too interested any more, doesn't really reply to my teasing and/or compliments. I know that I should ask her out and stuff, but she still lives in my hometown, and university is 120km away from there, so planning a date isn't so easy...

It has happened before to me that girls where asking for MY number, after which we chatted for a bit and things ended up nowhere. I know that I'm doing something wrong, maybe not escalating quickly enough, but I don't have the means to escalate it to a date for example, in this particular case. Where should I deviate from my current game, and where's the mistake I always seem to make? Hope you guys can help me...
