Was the ring still there, at least?

Best you found out that way than out in public esp. in a fancy restaurant with all eyes upon you....

You need to buy a bigger ring until she says yes.

I would make sure she wrote that note. 3 years is a long time to invest in someone that you’re planning to say no to.

AGAIN. Marriage isn't a surprise. You should BOTH know you want to get married, discussed it, planned to marry relatively soon, even planned if she wanted to pick the ring. The only thing that's a surprise is HOW and WHEN you propose. That's it. Marriage isn't a movie, it's a huge commitment that you should already both be on the same page for.

You should've hidden it from her.

uhm...im hoping you reconsider

I wonder what she did with the ring

Fml?, you dodge a bullet!. Why would you want to marry???
