I got rid of my whole FB account and a close friend a few weeks ago said: your H has the OW on his FB, do you want to see? I was so tempted but then I thought no - how is that going to help?
I saw my H recently and you know what, he doesn't look too happy. What you see on FB and on the surface is not usually the real thing. Get some rest and you can then decide what to do with FB.
