How to balance it...

I love Ballroom dance, but my boyfriend doesn't.

I was on the list of dancing performace, I am very happy that I have the opportunity to perform, but he deosn't, because it means I have to spend more time on preparing my performance, but less on him, especially after midterm exam.

In addition, he is very care about "Ballroom dance", because I have to be very close with my dancing-mate, some of our motion are almost stick together. I want to explain that when we are dancing, we thought about the steps, it's impossible that we have affection to each other. I can understand the reason he feels uncomfortable and jealous, but I really don't know how to do...
