"Well, we weren't together then, Tee."

Ah. Ah hah. Time to bust out the old essplainin'.

"See, when two people live together, and they're involved romantically, it's a big commitment. Not as big as, say, getting married, but it's still a big step. So when I said 'cohabitation,' it implied that you and I were serious about being together on a permanent basis. And, as much as I like you, Tee, I don't think either of us are ready for that. Not yet, anyway. Time will tell."
