Hi
@TheTruthWithin37
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
Blessings grace and peace to you
