M- The message you sent was not a message that would necessarily make her unhappy. You are spelling out your feelings, something I imagine that you have a difficult time expressing verbally (I know that I do!!). So she probably sees it in a positive light in that regard.
IMO, you have nothing to feel bad about. Telling your wife how you feel should not make you feel bad. This is true for all people. It is reasonable for us to expect our spouses to comfortably express to us how they feel, and vice versa.
