Same situation here, only reversed. Matt loves to dance and I hate it. Like really hate it. We started dance lessons on Monday night and I really am counting on it making me comfortable enough to be able to do our first dance. Otherwise, if that doesn't work, you might have to realize that you are marrying your FI for who he is, and that might not be a dancer. I hope things work out (my FI would LOVE to do a choreographed dance as our first dance, but is it hard enough for me to get up the courage to do even a simple dance!)
