Courtney, what a mess! Did you remind him that it isnt his home? That he walked out?
Instead of trying to be specific about what you are doing, just tell him that you have plans. You dont want to make yourself look bad in the event of a trial, remember. Be vague and mysterious.
So you lost your temper today. Eh, it happens. Move on, you have plans to go out and have fun tonight, do it!
I guess I gave the wrong finger to the wrong man...
