I'd say welcome to the club, but I'm sure it's not a club you wanted to join. I noticed one day when I logged on Facebook my married to W status changed to just married. At the same time I noticed she wasn't in my friend list anymore. Yes, it hurt. But I was also somewhat relieved. It may have been because I was tip-toeing through FB trying to avoid seeing anything that was going on with my W.
FWIW just a couple days after that, I started getting all these friend requests from people at my church. It's not her actions triggered this, either. It started with people who don't know my W that I've recently become friends with. Maybe you'll get a similar result?
You're on the crazy train ROMB. Trust me, it will get less crazy as time goes along.
