I wouldn't comment or 'like' anything on her account.

As far as whether or not you should 'defriend' her goes, that is a tough call. It depends. FB can be useful in providing a window into your life for your W to see how you are doing just fine without her. It is a great place to post some of what you are doing to GAL and even pictures sometimes. If you choose to use FB this way, make sure not to go overboard. You don't want to use it to try and make W jealous by posting pics of OW or anything like that. I believe that this can back fire.

Now the downside to be friends with W on FB is that it also provides a window into her life. So, if she is posting things that seem to make her life look grand and wonderful, this can hurt you. I've also seen a couple of bad sitch's where the WAS has actually posted pics of OP on FB. This would be devastating.

I have chosen to stay friends with my W. Early on, I used it as a window for W to see that I wasn't just sitting at home waiting for her to call me. So far, I have not been burned too badly with the view into her life. She periodically posts what she is doing, but nothing has been out of the ordinary or stuff that she wouldn't have been doing even if we were together.

Gotta use your own judgment here.
