What makes men come back to you?

Last year I had 3 dates with this very handsome older man, and we drifted away after I didn’t go home with him after third date. It’s been a year, I met him once accidentally while on a date with another man and then after a few months he showed up in my dms consistently asking me to meet up and even invited me to Thailand for a trip… I didn’t go of course, but I was wondering why did he come back after all this time? I felt rejected a year ago and moved on, now I no longer feel interested, I do enjoy the fact that the man who I truly liked is still interested in me, but I lost interest long ago. Why’d he back now? I don’t even reply his dms anymore.
