Oh, Mort, that is sweet!
My DH and I were already living together here in the UK - I was on a student visa - aside from getting a little more edumacated, the visa gave us a chance to decide whether we really wanted to be together. 18 months in, we decided to go for it, but I told him I wanted a ring we both liked AND a romantic proposal!
So, we shopped for a ring together. Once the purchase was made, it was up to him when/if he proposed!
Not long after we got the ring, we took a few days' holiday in Cornwall. Our first evening there, sitting up on the coastal path above a beautiful little beach, just as the sun went down, he actually got down on one knee (so we weren't sitting, we were standing!) and proposed. I can't remember his exact words anymore, but it was as touching and romantic as I could ever have asked for.
When we got back down to the little beach car park, we met another couple going to their car and he blurted out to them that he'd just asked me to marry him! That started a conversation, of course.
Later in the holiday, he told me he'd asked me then because he reckoned the ring was safer on my finger than on his person...hard to believe that was over three years ago, and we've now been married a little over two years.
