Thank you everyone so much, both for the advice, and for the well wishes. Sounds like the simplest solution is to buy something on the largeish side to account for swelling (like Ward, I do BJJ as well as lift) and take it off when training. I like the chain idea as well. Brian, I like what you say about putting it on every month, that's a really cool way to think about it.
My fiancee will definitely be supportive; she understands me and has always been tremendously encouraging of my lifting, martial arts, and music. An actual quote from her: "honey, stop washing those dishes, I'll finish them. You said you wanted to deadlift today; go downstairs and do that". She's been there to cheer me on for lots of PRs, her encouragement is the best "psych" I can get; I'm stronger for being with her.
The congratulations from everyone here really does mean a lot to me, I appreciate it and thank you all. Pavel especially for taking the time to wish me well; a strong marriage is the best thing I could ask for. I've been in other relationships, but never seriously thought about proposing before; a big part of why I did was because I knew our relationship was strong, and we could handle hard times, not just easy ones. I'll find a way to work the word "strong" or "strength" into the wedding vows!
