Congrats!
Here's my nickle's worth of free advice.
If there is a choice she's asking you about (napkin color, candle size, or shoe color) and it is of little concequence to you, avoid saying "I don't care"... it gets misinterpreted into "I'm indifferent to our future", causing tears, and thoughts of "does he REALLY want to do this, he can't even decide on how big the candles will be..... he hates me"
A simple "I trust your judgement" will pull your hind out of the fire.
I wish someone told me that.... I learned the hard way.
