FI and I both consider our second date where he took off his cross and put it around my neck and told me he wanted me to have it as when he proposed even though he didn't say "will you marry me."
There was unfinished business (long story) and I wouldn't let him officially propose until it was finished. It's still unfinished, but I realized that I was giving someone else power that I don't want to have any power so I told him that he could propose any time. He casually told me not to make any plans for Saturday the 21st. Well, since our first date was on September 21st I knew what his plans were.
I asked him if he'd made reservations yet at the restaurant where we met and he told me I was being nosey. I told him he was too predictable. LOL So, we took the kids to this little traveling carnival last night and I knew he was going to do it there. I felt around in his pockets and he asked what I was doing and I told him feeling for a ring box.
He really wanted to ride the little ferris wheel and I really didn't. I'm not big on heights and the little cars spin unless you hold onto this ring thing and even then they rock a lot. He wanted to wait till it was darker so the carnival lights would be prettier. I knew what he was planning so I caved and we got on. All the kids were on at the same time and no one but my oldest, who had already ridden it, knew what kind of ride it really was.
So, he proposed right after we got on and then all hell broke loose. This thing was the most terrifying ride I've ever been on in my life. It didn't look all that menacing while we watched it, but now I know why so many people looked so ill. I screamed the entire time and finally started letting the operator know, in non-kid friendly language, that if he didn't stop this thing, I was going to vomit all over his precious ride.
It was not one of my better moments. I really did totally lose it. I have marks on my legs where the lap belt dug into me as I was lifted off the seat each time we plummeted and marks on my hands from having a death grip on the ring that didn't do a blasted thing to keep us from going upside down and round and round.
I crawled out of the ride and promptly sat down on the grass. FI joined me and that's when my oldest snapped this pic:

At least I know I'll never forget when he "officially" proposed. I should have kept my mouth shut and let him do it at the restaurant LOL
