I don't think I would have agreed to sign papers because you don't know what they will say. Also, what is the D procedure in your state? My opinion, is that if you don't want a D, then don't make it easy. Not that you should actively try to stop it, just don't do anything to facilitate it.
Anyway, I think in your sitch and based on what you wrote in my sitch, that two things are going on. First, your W clearly has reasons based on your behavior, which you can change. You should do 180's on some of the things that clearly hurt the relationship. You should also follow Sandi's 37 rules. Second, the excessive exercising you mentioned in the post on my sitch is one sign of a mid-life crisis (MLC). If your W is MLC, then everybody says it can take a long time. Something to be aware of.
