That's weird. I had my wife try it right next to me and it took her to my page. The problem might be that facebook is asking everyone who has an account to send a picture of themselves and unitl they say its okay you cant use your account. Just because they want to make sure your account is real or something. I was on my facebook this morning thats why i posted the link but now it looks to be useless.
If you are trying to share your private FB page then you will need to check your settings to ensure they are set to public viewing. Your wife could probably see your page because she will be a 'friend' of yours on FB.
However, you will need to think and pray about how "public" you want to be in this world of scams.
If it is an article you are trying to share, then open the article and there will be a separate link which may or may not be accessible to all
