I Don't Want a Wedding Now, Fiance is Mad

Fiance mentioned wedding, coming up in 6 mos. I told him we should wait, or extend it. I started a second job, I just moved, and I’m still getting used to alot. Plus, he just started a new job, and I signed a lease which I’d have to break if we get married at the original date. We haven’t sent out invites, nothing. We don’t have savings. I’m realistic, and def not in the dream wedding mood or whatever you would call it because I’m also looking for a new job in a new state, which he was going to move with me to. So as you can see a lot is going on. A wedding is the last thing on my mind. Plus we both have to lose weight since we gained weight since being together. I have gorgeous clothing I’d like to fit into and he’s gorgeous, chunky, but also has to lose weight. So to add all this wedding to the already ton of things I’m adjusting to is not something I want to do. And although I’ve never wanted to do a court wedding, that’s looking way more attainable than organizing even a reception in the back room of a restaurant.
I was never someone who needed ice sculptures of a live band. I will take someones back yard. But we don’t have savings, we both started work, and my second job is even harder than the one I already have. Yes, he has a second job as well.
I tell him this and he jokingly asks for the ring back. Then jokingly mentions for the rest of the day how I don’t want to marry him. So now, I’m annoyed and really don’t wanna be bothered. Someone help me understand what I’m feeling. I would’ve JUMPED at the chance just a few months ago but life has changed SO drastically and SO quickly, I can’t keep up..and he’s willing to pay for the entire thing! Help…
