How do you like something you hate or dislike doing?

I cook. I may not be regular cooker, but I do enough to survive. I'm not in love with cooking either.�However, I'm getting married in a few months and I have a fianc� to feed. He's a very picky eater and doesn't like to eat the same food in a row. I don't know what to do cause I barely cook now and we live together. I'm trying to get him to learn how to cook too cause we're both from different cultures. I don't know what to do! What can I do to be a better cook, but at the same time enjoy it? My fianc� tells me that I have to like cooking in order to be better at it.....
