Good call on not mentioning the ring, you are getting the hang of it.. that was VERY GOOD to just let it go... if you had made an issue of it she would have removed it and you would'nt see it for a LONG TIME...
Your wife needs to approach you at HER PACE and you need to be very careful not to scare her off my staying calm... think like feeding squirrels in a public park or something... it is a great way to understand the process... go feed some for practice.
