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

No, it's definitely not a coincident. Sounds like she isn't really that into you but liked the extra attention she was getting. Now she's not getting any of that and is probably a little jealous (of not getting attention from you anymore), and enlisted her friends to find out any info they can from you.

Some girls are like that. They are flattered with the extra attention you give them, even though they don't really want a relationship with you.
