Good to hear you are moving on. Sorry about the financial ruin, but you have the ability to rebuild.
It sounds like you dont need to be too concerned about the OM much as he is a spineless worm that can be controlled by your STBXW. It sucks that your D13 despises him. That in itself does not sound like a good way to start a trip.
If your W is not telling you about OM going on the trip, then that is just another thing she is being sneaky about. Let her continue to be sneaky as it is not worth pointing out to her. I think as long as you can be friendly with your STBXW then it will allow for the two of you to move on through the divorce with minimal pain.
