Surprise! You’re the “other woman”.

never said my divorce was final

Listen. When I took you out to dinner and brought you home, I thought you were doing that with the knowledge that my soon-to-be-ex-wife will be stopping by in the morning to pick up more of her stuff. Oh, and please disregard her panties hanging up to dry in the bathroom. You didn’t know I still had a wife? Well. That’s your fault. You should have checked my facebook  relationship status.
