Did I Ruin A Marriage Proposal?

Me and my boyfriend were drinking Saturday evening and he proposed to me 12 times before bed after delivering this long speech. I told him to ask me another time when he was sober because I knew he was exceptionally drunk (I said it in the sweetest way possible).

The next day he brought it up while we were drinking coffee talking on the couch and he asked me again but I wasn't 100% sure if he was really asking (though he clearly said "So Will You Marry Me?") as I just assumed he would do the ring and down on one knee thing (which I would say yes if he did). So I took it kind of as a joke

Background: In the past we have talked about marriage and agreed we would someday, and we also discussed that I really want a private, couple people, outdoor wedding as does he. So the topic has been brought up before...

So if you could answer any one of the three (or all three ideally) questions - it would be helpful!

1) Was I wrong to assume that he was joking when he asked just because he didn't give me a ring/get on one knee? Was that a real proposal?

2) He hasn't said anything even like that since. Did I screw it up? (Like would he think I was saying no to marrying him?)

3) If I didn't screw up my chances, how do I let him know that though I don't want a big wedding I still want a ring (doesn't even need diamonds) and a real down on one knee proposal?
