So she's crazy. (all she had to do is tag him in the photos and they show up in his)
The world will go on without FB, many people here have had to get out for awhile and some never return. You can do this, M!
You aren't crazy but right now you are letting all their actions dictate what you do.
Find out today what your rights are as far as the house goes. If he doesn't have a right to walk into it uninvited, inform him of that in the most peaceful way possible. If he shows up take whatever action is suggested to you.
Talk to the kids, tell them you will take care of them and make sure they are safe. Don't run down their dad or the OW.
Your H and the OW are not problems for you to fix, let them live their lives.
Your problem is to find your path and walk it. You can do this.
Don't know if you've attended AlAnon in the past, if not try it . Give it 6 meetings. The people there can help you. If you have and just haven't been going, get your rear in a seat!
Get your kids whatever help you can.

Let me give up the need to know why things happen as they do. I will never know and constant wondering is constant suffering. Caroline Myss
