Having to deal with all of this FB stuff is going to be tricky I have a feeling! I think that I will set it up so that I can't see any of my H's posts, not that he posts anything anyway, he is a pretty private person. I have a feeling that anything he does happen to post is going to bother me though! lol.
Honestly, though, I don't know what your H is thinking, posting a photo of him and OW on there.. doesn't he realize that your son will see it before he has even spoken to him? I hope he has his talk soon.
