Does She Like Me\should I Ask Her Out?

Me and this girl met this weekend at a speak off competition and I felt like we really hit things off well. We hung out for the majority of the weekend: we ate together, sat together, she dragged me around the mall, etc… So when it was time to get on the bus to go home she asked me to save her a seat. So I did. She told me she wanted to get some sleep so I was quiet and then she fell asleep on my shoulder. she slept on my shoulder until we got to her stop and then she wasnt off the bus 5 mins before we started texting again. In a text she said ” if I had a choice I’d still be passed out on you”. Anyways we have only stopped texting yesterday while she was at school and as soon as she got home we were chatting again. In our convos she is always telling me I’m sweet, adorable, amazing and so on. And we keep saying to each other that we want to meet up as soon as possible. Sad thing is she lives about 3 hours away. Does she like me? Should I ask her out? If yes, how long should I wait before asking her out? Thanks OH and btw we are both only 16!
