Sarah I was married before as well, and I didn't see my ex the day of until we walked down the aisle.. Well, come to think of it, he was at my house and he refused to leave until after midnight so maybe it is bad luck.. :-)
Anyway, just do what feels right for you and your FI, that's all that's important, shoot Cain and I are going to get a couples massage the morning of our wedding together.
