Cause ever since I left the city, you
Started wearing less and goin' out more
Going to places you don't belong
Why you never alone
Used to always stay at home, be a good girl
So what I'm getting from this song is the guy becomes suspicious of his girlfriend going out more and automatically assumes she's cheating because she doesn't want to be stuck at home all day while he's off enjoying himself.
Granted, she could probably call him more often but besides that, why should a grown woman be told she shouldn't go to places she "don't belong?" he doesn't even mention her seeing other men, just "girls I never seen before" - so? Is she not allowed to go and make new friends?
I absolutely hate that this song is popular at the moment; people listening to it seem oblivious to the possessive overtones and it pisses me off.
