I've met a girl when I was visiting my friend in his dormitory. She was clearly into me - she even made us a meal because I was hungry at 3:00 am. My friend wasn't even invited at first but he came anyway because I didn't want to leave him alone. Because of my friends it wasn't possible to escalate. She invited us for some home made meal in the next week (again, she was only looking at me. I may be wrong but I think that it would just be awkward to invite me only when we were sitting in my friends room). Next day I texted her thanking her for the free meal and great time. We texted a little bit and it's looking good. We are both leaving for a week so I won't be able to meet with her in the next few days. The question is: Do I just ask her for her number via text (saying that I want to meet with her in the next week) or continue text game? I don't want to give her too much attention without but on the other hand I don't want her to loose interest. Obviously I am busy so it takes some time for me to respond.
