Oh yes, I had a similar thing when my b/f was away for 3 weeks recently. She was a nightmare!!
She wouldn't come to sit on the bed at night, instead she'd search the house then when she was done she would sit down wherever she was and cry until I came and picked her up.
She followed me around the house during the day, if I closed the bathroom door she sat outside and cried.
More than once I found her trying to pry open my b/f's wardrobe door and also cirlcling his chest of drawers.
Then if I was using the computer she'd sit under the chair and whinge. In the end I got her a dining chair and put it next to the computer too - she sat on that and went to sleep.

But I have to say it wasn't all one way.... if she was settled somewhere I had instructions to point the web cam at her so 'someone' could see her from his desktop pc, 7 time zones away!!!!
Even the other guys in the office started asking when the cat was going to be on next! lol
