Nothing that you want from this girl will happen this weekend. You may get some action sure, but you will not be her boyfriend, you will be her boytoy. That's not what you want, so leave it alone. You're going to meet up with her and if a better deal doesn't come along and she's horny enough, she'll bring you home, you'll get some action and not hear from her again and you'll be right back where you started, here asking us why she doesn't call. If the girl was interested, she'd make time for you. When I started going out with my girlfriend last year, since I was interested in her, instead of going to Alumni Weekend at my college with a bunch of friends for a great drunken time, I stayed home that weekend to go on our second date, I knew I wasn't going even get any that weekend, but it was a great decision that I don't regret. If someone's really interested, they will make time to see you.
