Is texting leading someone on?

I have a good guy friend who I often hang out with and we sometimes text. I love texting him and we get along so well.I know through other friends that he is interested in me. I can’t pursue anything with him as I am not in a place to date (even though I am crushing a little). I have told him previously that I can’t date. Is it leading him on to keep texting him regularly? Nothing flirty just general chat that he often starts.

Thanks in advance.
