FB, IMO is not a good indicator of what a person or relationship is like. People often put their best foot forward on FB. I know of several examples in my own life- One is a a couple who post constant pics of each other together, they have been married for 19 yrs. She posts about thanking God for a good husband. A week after posting that she came to buy a couch from me for her new house because they were seperating. I was like wow that is sudden she said no we both had affairs and it has been bad for years, we made the decision to seperate about 6 months ago. I know I must have stoood there with my mouth hanging open.
Another example I know a guy who has not seen his children in several years and is a terrible father. He doesn't visit, call or pay support. But on FB he is the greatest dad on earth. He posts pics (that he copies from other relatives fb) and writes long loving posts about the kids. People on his fb say things like "your such a good daddy". Makes me sick and takes all I can do not to say something as I adopted one of those kiddos that he posts about.
