Is there anyway you and fWH can get rid of LinkedIn for awhile? I mean you can always go back and do these pages in the future right?
Are you guys in MC and/or IC? Being able to work through the anger and marriage troubles is great in MC, and IC can really help with letting go of what you cannot control (OW looking you both up on the internet).
I found limiting OW/xBFF's access to me very freeing from her in the beginning. Recently, her daughter found my old YouTube account and it did trigger some feelings I wasn't expecting as I can only assume OW/xBFF looked at the page as well. But, it only took a day or so to get it out of my mind and not really care at all what she is doing.
Until you remove the obstacles that continue the triggers they will not quit. Maybe not all people here would agree with me on that, but it worked tremendously for me (as well as being in MC and IC).
