is this conicidence ?

[Francois]

I asked her out three times but her answer was I don't like anybody. I moved on and 10 days later I blocked her on facebook( I just wanted to get over coz I keep looking at her profile). 2 days later a classmate whom I don't know at all ( he is her best friend, they always hang out together ) adds me on Facebook. is it a coincidence, I mean I never talked to this guy and he her best friend I dunno ?

note:
1-her friend ( female friend) asked me if I am in a relationship or not ( before my confession)
caught her friend whispering in her ear and 1 minute later she came in to me with her friend and initiated a conversation ( before the confession)
2-one day after the confession her female friend sent me a group link and my crush is member of this group.
3- after she rejected me the first time I posted some random staff on the group late at night and after half an hour she commented on an old post ( It Is not my post but I still get the notification) and I am sure she made it on purpose to grab my attention
