Is my ex checking up on me to see if I am still single?

So I recently ended a 3 month situation-ship kinda thing with this guy, we had started off as good friends, but just realised that ultimately we wanted different things and were just in different things. We ended on good terms and agreed to stay friends as we are in the same friendship group. We ended things a few months ago, and are civil when we do see each other, but are not overly chatty. I do notice he does tend to stare at me a lot in group settings

Recently, having re downloaded a few dating apps, one of his friends (not part of our mutal friend group) liked me on facebook dating, but never messaged or anything, at the time I didn't think anything of it as I had never met him and only recognised him as my ‘exs’ friend from his name and the fact that we had him my ex as a mutual friend. But I did think it was a bit odd.

A few weeks on hinge, my ex’s roomate then popped up on hinge briefly, I had met the roommate briefly in passing and thought it was a bit odd he was on hinge as I know he was taking a break from them. He did also like me on hinge, but i declined the like and haven't seen his roommate on hinge since, and still have the same settings, so thought this was odd. I did briefly block my ex on hinge, just as seeing him pop up all the time was a bit triggering for me as I did want to continue the relationship but he didn't, so did block him to move on. Probably overthinking this one, but i did have the brief thought that he only did that to confirm if i was on another dating app

More recently, a mutual friend mentioned briefly that my ex was struggling on the dating apps and was having a hard time and asked how my dating life was going. Again i thought this was a bit weird, as far as i know we hadn't told anyone in our group that we were seeing each other in case it didn't work out.

i just found it odd, that three separate people have seemly ‘checked in’ about my dating and don't know if i’m being checked up on to see if i’m still single.
