Is this coincidence, stalking or am i over thinking?

[Susan]

I told my crush ii had feelings for him through facebook messageing because he is in another country.

He never responded, so i assumed thats a reject and he is not interested at all anymore.

so i tried to move on and forget about the sitation, but two of his friends added me on facebook.. who i dont really know all that great but i accepted them anyways.

i decided to delete facebook because i just need to move on from all this drama and start fresh..

so i got on another Social media website and his friend follwed me again and then commented on one of my pictures droping my crushes name.. for and example: "OH do you remember when me and (my crushname ) blah blah"

i politely replied being nonchalaunt. then his friend started complimenting me and hitting on me...

my question is... is this all a coiencidence or is there any correlation on going here??

Please answer i need insight on this.
