It would be better if you didn't. Do you have any anti-anxiety meds you can take beforehand?
REHEARSING it, even out-loud, ahead of time, really helps too. That's what I did. I gave my "speech" out loud, about 20x, in my office with my door closed, even gesturing and pretending I was making eye contact with my wife. I VISUALIZED myself, strong and confident, anticipating her objections and how I would handle them.
