Yes. Her actions will drive you mad. It's hard being nice when someone is being so obnoxious but WW's are really good at this whereas the LBH will want to hit out verbally or otherwise through frustration. You just keep your head mate.
If it's any consolation I am fuming right now as my WAW is strutting round the house all calm, texting God knows who, as I sit with the kids - once my D8's piano lesson is finished they will go to her house and I will be alone again.
You go through cycles of grief if you don't occupy yourself. I think there's a bit of devil makes work for idle hands and tongues.
I feel your pain. Keep your head. You can do it. Don't let her in your head - keep it occupied so it is not available for her.
