IMO, you might have to think about dropping the D papers. At least think about it as an option. I think you are looking at D as the end of you'll relationship. But she went on a 5 day trip with OM, and you didn't object. She moved OM in your home did you object. I'm scared to give you this advice, because you want to keep the door open, and I think you think D is closing that door, but it's not. It's a piece of paper. You are holding on the a W, that don't want to be held on to, at least in her mind right now.
You are doing a lot of mind reading. We all do it, but if you are going to get better, you have to let her go completely.
Her respect for you is at an all time low. Do you still pay a mortgage at the house your family stays in?
IMO, I don't think your wife thinks you will walk away from her (let her go completely). She stills thinks she can hold on to you. You have to take that away from her somehow. How can you do that? And do it with love.
