Laying Deep

Talking to one of my dear friends one night, and discussing our past and current relationship, he gave me a quote.
"If you broke up that long ago, and you still cant keep from thinking of her, and still care enough to have a tear brought to your eye, dude, I`m sorry, your not whipped, you could be in love...."
I do believe that it is possible to love so much you just can't live without them, but to run so deep that there is nothing left in your heat, no room for anything else, is it possible? Just think on it.
