How much does she like me??????

this girl and i have been talking for like a year. she said yes to prom last year, but couldnt go bcuz my friends limo ride was $300. well we've been talking since then.we went to a sports banquet this last saturday, and she brought her mom over to meet me. well she asked me to put pics up of us, and we always text till we fall asleep. she always asks to hangout. and we're going on a double date next weekend. if i dont see her for a long time she'll ask me if i miss her and stuff. yesterday i gave her a gift bag for valentines day, and she said, "awwwww thanx." and this morning when we said bye she gave me like a 15 second long hung. she's 19 im 17
