I have been afraid of that. You think my wife might just see me as a friend?
I can't answer that for you. The only person who can is her. If she's becoming more friendly, etc, without anything else, then it's entirely possible. My ex did that - what I thought were improvements: talking, laughing, touching, etc...anything that I perceived as small steps were ore than likely nothing more than her becoming comfortable within herself and the situation and leading to the dreaded friendzone.
There are moments in this life when you are so confident in the rightness of your actions, that not even for a second do you consider the option that you might be wrong.
