Would you find it strange that your husband had blocked his friends list on facebook so you can’t see it, however you can see mutual friends when you click on them so I can see he is friends with someone people we both know, and when I click on other people he knows but I don’t have on my facebook same again he shows as mutual friends apart from one girl who I know he is friends with as they chat all the time on facebook (old friends)
To me it looks like he has blocked me from seeing they are friends, why would someone do that?
