Basically, I had met a guy online and we are never mets. I have never spoken to any of his friends as he says that he didn't want me to talk to them as he doesn't trust them.

We broke up this year.

I had a guy added to my insta account who happens to be added to my ex's account too. Now, I never spoke to this guy nor does he know about me and my ex., so basically we are just strangers who follow each other on instagram.

After so many days, me and my ex were talking on insta today and suddenly I noticed that the guy has blocked me. (At first, i assumed that my ex noticed that he is added so he might have said something to him)

I asked my ex about the same and he said he didn't know thar someone acquainted to him is added to my account.

I am just confused with all this. How come without any conversation someone blocked me that too on the very day I spoke to my ex.
