Does this ever happen?

I got this friend from my second year in high school. Back then I was pretty hostile and easily pushed people away, he texted me via a social group and I felt he was invading my personal space so didn't give him much attention. Fast forward we became friends and he had usually text whenever he had the chance to come home from boarding school. I was also in boarding school so he often ended up chatting with my sister. About a week before we completed High school, hw asked for us to be together and I declined. High school ended, we went to different colleges in different cities and we were still in touch. We're both done with school now, each trying to work around our career, I was quite not stable mentally last year so I went off for a whole year, upon my return nothing seems to have changed with the exception of he telling me I left him all alone. It's been 8 years and over and we still haven't met in person, seems we're not bothered by that though but does this friendship look like it's going far?
