Personally, this guy is smart in that Facebook has personally led to more breakups and couple confusion since inseption. Outside of that, quit spamming the creepy vibe by thinking his actions are creepy. Talk to the man like a human being, feel out his vibe. Spit game if he's vibing with you and go play in the mud or something. That facebook request thing didn't even happen far as I'm concerned. Feels like a chick that didn't pick up during a phone call and it went to voicemail.
YMMV, pull trigger hard.
