He sent me a friend request early morning and I accepted but he didn't message me until late night. Why?

The entire"he might of been busy" is out of the door because he was online.

Guys, why would you add a girl on FB?

Would it also turn you off if you seen her "guy interaction" on FB is somewhat high (meaning-constantly somewhat "flirty"). Would that make you jealous and perhaps in need of more attention from her because you wanted to get to know her (reason why you sent her a request in the first place).
