He's gonna make you sweat it out waiting but when he proposes I am sure it will be a beautiful surprise. That being said, just keep the hints to a minimum. Can't wait to see once he finally pops the question.
I "found" my engagement ring while cleaning Jim's office. So yup - totally understand about ruined surprises. Plus I had to wait to get it and not tell him I found it. Which was agonizing. Then I ruined his surprise even further because he wanted to propose when we were in Vegas but before we left on the trip I had invited my parents to visit when his parents were in town. So he felt he had to propose early so we could tell our parents. So yup - I feel your pain.
Luckily Jim picked a beautiful simple ring, but I could understand not needing to wear something you wouldn't ever feel comfortable with. Hopefully what he picks will be gorgeous.
