Try this.. buy a date book, cook a nice romantic dinner and (over candle light) tell him that you’re not going to allow your terrible memory to cause you to miss one more important date between you…. With your new calender in hand, say something like “Here’s how serious I am … I just bought a date book, would you please go through it with me so that we can note all of “our days” together? I don’t want to miss anything important, again. ”
I bet he’ll be touched.
And I’ll bet (if you check your date book daily) you won’t miss another important date either.
