Elopement help ??

My partner and I have talked about getting married soon and eloping. I don't have friends or family for a big wedding and just want something small and intamate with just our parents and grandparents.i have basically found a venue and planned the decor for our ceremony arch, bought a dress etc . All we need is rings and our marriage license. Well Everytime I mention it now it's always oh I want this big wedding and invite everyone , I want to buy a house first and have the wedding in the backyard and seems like he just is trying to prolong it now. We've been together 4 years now and it's honestly disturbing me that we can agree on shit, and now he wants to buy an expensive ring and have this big wedding I am not intrigued by at all. I don't care to entertain and feed hundreds of people who I dont care for and people who don't even talk to him but he wants there. It's our day , so I just don't get it. After all of this Bs after we discussed to just elope is making me not want to marry him at all anymore. It's not a beautiful process , I'm simple I don't want or need much , just the two of us is all I need on my wedding day. I know it's wrong but if I can't figure out how to get him on board with things and get the process moving I'm leaving him. I'm tired of wasting years with someone who really doesn't have the same values ,that's what it seems like since it took him years anyways to be on board with marriage. What can we do to try to work together in this situation. I just want to marry the man I've lost a son with , someone I've shared my heart and life with and he's making is hard I just don't see myself staying if we don't get married, especially after all the planning we've done already . It's like I'm being stabbed in the back .
