Was it too soon to ask her to be my friend on FB?

[Respectedcalculator525]

Hey, so me and my best friend went to my friends youth group
it was my first time going so i met this girl and i was really attracted to her...like im usualy not easily attracted to girls...especially when im with my female friends but this girl i was attracted to...like i think it was more of her personality so tonight i went and it was like a dinner party thing and she sat at our table and her and i talked for a minute or two., then my best friend meg was like...I think she likes you because shes flirting
then she left the table (cuz she had to help her friend with the dishes)
so then after words i kept bumping (literally) into her like 3 times and we kept like laughing and flirting....so when i got home i looked on my fb and i saw that my friend (PJ) wrote on my wall. so i went to go reply on his wall...and then i scrolled down and saw that the girl that i was flirting with was the last person to write on his wall...and i added her...then after i felt SO stupid like its too soon? we hardly talked UGH
