I think it's very natural that part of you is a bit disappointed that your wife is different from you. We all like to find out that people who are important to us are the same as we are.
As you say, you don't wish it on her, and I'm sure there's another, much more important part of you that is happy that she is who she is. Just remember: you presumably married her because of who she is, and if she were on the spectrum, she would be a completely different person from who she is!
