What happens now?

I met someone online when I was younger, we text, sent pictures etc. we live in the same country but long distance, like 10hours apart, we have never met in person. After a few years we stopped talking but remained friends on socials. We’ve both gotten married, had a child, one had a divorce. For the last two years we have been in touch daily sometimes for advice, sometimes for sexting and even just a catch up, one of us has recently remarried. Is it wrong that I lust after the guy I met on the internet over two decades ago? Each and every day my heart aches to think that he was the one that got away.
