Yes, it is very sad, both for you and your children. I really believe you have done your best to protect them and show your support of their feelings. Unfortunately, because of W's choices, they cannot be protected from everything. The only thing in this situation you can control is your deep love for your children. You are doing a great job with that!
This thing with the OM is obviously going to die out. I think that you realize that. I think it's great that you let go of control over who picks them up and called her bluff. Looks like it played out exactly the way you thought it would. Now, just keep it up. It may fizzle faster than you think.
You're doing and saying so many great things! Don't let her bait you. She was obviously looking for an argument when she texted you. I think she already knew that OM wasn't going to do the driving. She was just trying to make you the bad guy when she didn't pick up kids. When you called the bluff, it left her responsible again.
