Is my high school ex coping me but doing it with someone else

My friend from HS pointed out how my ex seems to be living a life close to mine. I moved to a part of town 40 mins away which my ex knew about cause he once offered to meet up for coffee and I declined because I lived in xyz and he said he can meet me there since he’ll be driving past it on his way down which I still declined. And Snapchat so he knew the places I post. I moved to another state for a year then moved back. This dude moved to the exact same state for a year then moved back andguess where he lives now, 10 mins from my old place which is 40 mins from our hometown. And apparently his gf works 3 mins away from my old apartment. Also him and my other friend recently became mutuals on Facebook. I’ve tried to mind my business but it feels like this dude is following my breadcrumbs
