Why does my ex still come to my work?

I work at a clinic in a different city where there is RMT services and I got him to come there at the start and he broke up with me 2 months ago and I removed him off social media, we haven’t talked since. but he still drives out from the city to see the rmt at my work. Is there a reason (when he could find lots within the city) or am I over thinking this.
