Dude, you need to
stop
stalking this poor girl. You freaked out because you convinced yourself that some time off she took coincided with some time off another male employee took, and had this whole freaky scenario going on in your head.
I sure wish I knew her so I could warn her about you.
It is impossible to live in the past, difficult to live in the present, and a waste to live in the future.
