What does this meann?

so theres a girl i like and to say we text alot is an understatement. the texting is really flirty, and we text several hour everyday (for abotu a week and a half now). I have always thought that this could mean that she likes me since we text so much, but when we decided to say nice things about eachother, she said "youre the best person to text". Could this mean that she texts me cuz im "the best person to text" and not cuz she likes me, or is it a sign she does like me? btw were juniors in highschool. thanks alot im really confused.
