Been following your story and I feel for you. Hang in there as you are clearly the much better person. As for FB, I actually blocked my WAW (not before unmarrying her) simply because I did not want to know what she was doing. I did not want to see about her life or anything. I am not a big FB person and she is really a heavy user. I do post pictures of my kids when we are out doing activities and her parents always like or comment. So I know she probably sees them. On the other hand, I see nothing and do not want to see anything she does. It makes detaching much much easier and keeps the mind from running wild with assumptions.
Best of luck to you!
