Stuck :/

Before my fiancè and I got engaged, we were together exactly one year, we got engaged September 24h of this year. I told him I didn't want to get married right away, due to the cost of things. He threw a hissy fit like you wouldn't believe. We're only 20 years old... I don't want to hurt his feelings.. I don't know if I should just go ahead and have this wedding, or wait..
