Fiance wants to elope

A few days ago my fiance asked to elope right then and there. He was so excited about it, but I wasn't sure because I've been planning an elaborate wedding for the past 6 months. He said he just wants to be able to call me his wife already and that it's killing him to wait. I thought about it and turned him down. He was understanding, but I feel bad. It's not that I don't want to marry him right now, but I want to have a wedding and have the memories and pictures from that. He suggested eloping just us and then still having the wedding as scheduled, but I don't know. I have friends who did this exact same thing and I didn't care. One because they wanted to be married before living together and the other because they were having their wedding abroad. Something about it being MY wedding though, just makes me unsure. Also, the date of our wedding is important to me. I don't want it to be on some random day. I'd perfer it to be on or near a date that's special to us. Am I overthinking it? Should I compromise.
