how can you tell if a girl likes you through texting?

ok, i feel like a huge loser for doing this. i dropped out of school around january and i currently attend night school.(not many girls) so i started talking to a girl from my old school. well where i would usually get to see them and actually make contact i cant. so text messaging is the next best thing. well we text every day. well about a week after we started talking she told me who she liked. i asked. (bad idea) well i kept talking to her and about three weeks hav gone by and she will get kinda mad if i don't text her when im supposed two. (as soon as i wake up in the morning) she texts me a soon as she gets out of her sport. and we talk till one of us is ready to go to bed. welp thats basicly it you think i got a chance?
