I think this is the first time I've posted on your thread. Just wanted to say I'm sorry for your sitch. Our timing is very similar and my H has filed for D, so I'm headed in same direction as you and it's very difficult. Wanted to say I'm pulling for you.
Also wanted to add my two cents about Facebook. I waited a very long time, but I had to block my H, the OW and all of my in-laws. Just too painful to see what they were posting. I gently explained it to my BIL. Haven't regretted it once. That would be my advice. No need to add to your sadness. Stay strong.
