Guy to Girl Question, I needed to add more to the old question.?

So there is this girl I have been really talking to latly. We started talking every night for the past like 2 weeks. We hang out almost every Friday night because we go to dinner with the same group of football kids, maybe like twice we were at the same party. She always says Hi to me in the hallways and always walks past me at lunch at taps me on the shoulder. We talk on AIM like every night. Her friends have also been talking to me more recently. I asked where she was at lunch the other day, and she said she came late so I said "well I basically waited for you" and she said "Awww", which sounds like a pretty good sign. So what do you guys think, does this sound like something a girl does to give a guy signs they like him? I have been thru this before, and was hurt deeply by it, so I want to make sure she really likes me first. She just broke up with a kid on my team like 2 weeks ago, and she went out with one of my friends last year, they are both really thin and I'm 5'11" 205lbs
