What a puzzy!
Basically you have become the woman in your relationship and she is the guy. You "think" you care about this chick because her wrecklessness excites you; much like how a woman feels with a "bad boy."
No guy with a pair takes the time to see who "likes" his woman on FB. As Salty said above, the guys who are trying to get in her panties now aren't liking her they are sending private messages that you know nothing about. THOSE are the guys who are hittin it, not the fools who like her page.
This is the type of chick you keep in your stable but you never really claim her. You knock it out when you want some and go on with your life when you don't. Is she still givin you the behind? If so, who cares what she does when you aren't around her.
Lastly, has this chick ever tried black?
