If you like each other, there's nothing like "texting too much" in my opinion. Do whatever feels right and be yourself.
I don't think the amount of texts always show whether you're interested or not, but also the quality of the conversation: asking deeper questions, paying attention, showing you care, keep the conversation going, etc.
