Do you think people who have no sign of their BF/GF on facebook are more likely to be keeping their options open?

In my experience, this is usually the case. I mean seriously – if you think the girls cute and you find her on Facebook and see a profile picture of her standing next to somebody who must be her boyfriend, it's a pretty good indicator that she's taken. But the girls I've known who are very flirtatious, or have even dated me before I'v found out they have a boyfriend – they have no evidence of them in their life on Facebook.
