why would a guy block a girl on facebook?

[Brianna]

I work with this guy who I went to high school with. I creeped before I worked there so I know I could see it.
Anyways, we get along well and work together a lot and I kiiind of like him, but he has a gf so I just go on with my work (stupid to even try flirting since he is my boss and has a girlfriend. no bother). I treat him like I do everyone else.
But I went to add him today since why not and I found that I am blocked. Why would I be blocked? I REALLY don't think he hates me..? We can joke and stuff. So I'm super confused.
He is friends with other coworkers so it's not just a boss who doesn't want his coworkers seeing his fb thing either

No reason, could be a glitch? Sometimes computers say something not true. Ask him about it, if it's a bad reason, then you tell him what you want to say. Maybe you were flirting but you didn't know it? IDK.

may be due to some reservations.

His GF hates you.

[Sum Ting Wong]

a smart man never gets to friendly with other women if he wants to keep his gf happy

He probably senses you have a crush on him and hes simply being smart.

Maybe his Girl Friends on to you, The only person your fooling is yourself, You like like him (Okay using language I assume you use), You would like him for yourself and he or his girlfriend are blocking you so you don't get to close.
