My ex followed my new crush? why? and he knows who he is to me …?

so when I was with my ex , before he became my ex, he brought up a guy that I used to talk to before we made it official.

I didn’t understand why he was asking me questions about him, as far as like what I knew about him, and he brought up the fact that was Arabian. it was a long time ago. It’s a really hazy memory, but I remember him kind of probing me about him.

Fast-forward 3 years later, my ex reaches out to me to catch up and ask for a friendship. Then will we begin to follow each other on social media , I noticed that he also just followed the arabian guy from years ago on Instagram as well…

they literally have nothing in common like they’re not even the same type of man, they don’t have the same type of hobbies, or circles, so why is my ex after all these years following that guy?

background info : he became my ex because I left him. also, ever since then he’s been trying to be friends with me, he ended up having a child with a woman that he gives my personality away to. Like he’s supports her financially so that she can do what I do for a living. Same career path as me , same hobbies as me, same car. It’s like he wants to make her me and she goes along with it.

And now it looks like he’s trying to be friend the guy that I used to like because he thinks I still like him? I’m not sure? what do you guys think? Why would my ex after all of these years reach out and do these things? why does he Still know who that Arabian guy is and follow him online? They have nothing in common. It’s just weird that he’s there looking around.
