Are my ex boyfriend’s friends stalking me?

Anonymous
Hello everyone
I had a non-committed relationship with a guy for 2 years. For him, I was his friends with benefits but it wasn’t the case.
I only met his friends at the beginning, because at the time I assume he wanted me to be his girlfriend.
He said he never talk about me but as time goes by, I discovered his bestfriends knew about us, his girl friends, etc.

We broke up for like, the 5th time, and I declared my feelings to him. A few days later some of his friends suddenly followed me on instagram (his sports coach and his best classmate, and two other friends), but we don’t know each other. I guess it can be just big coincidences, because I have quite many followers and they just might found me.
Do you think guys can do such a thing, like talking about a girl they had an affair with? And why telling about my existence if he doesn’t care?
Thank you for your opinion
