Girls, how would you feel if a guy only talked to u on fb? (but u know him in real life)?

I really like this girl and we would talk abut to each other sometimes fool around with each other during this cl, and then suddenly our communication dropped (guessing cuz she hangs out wit her friends more now...) so now I just say hi to her once in (I am very shy), I only talk to her when she is alone but she is always hanging out wit her friends now so it is kinda hard for me to talk to her, so now I just talk to he on fb (tiny conversations...very small, barely even a conversation). Since so ring break is coming, I thought I would have more time to talk to her on fb, but I advent talked to her in person for a few weeks, if u r a girl, how would u feel bout this?
