I don't think it's stupid at all. Have you told your wife these feelings and how much you need and want her support? If I were you, I would show her this post. It sounds like you want to build on your progress (quitting drinking) by taking another positive step (working on your relationship). I bet you got sober in the first place to have room and energy in your life to work on other areas of your life.
And congrats on 93 days! That's inspiring in and of itself.
