I just wanted to chime in and tell you that if you decide to do so, it is okay to let go. It takes more strength to let go than it does to continue to engage. If I'm reading this all wrong, feel free to tell me, but from what I read and gathered it just looks like this whole thing is taking a toll on people that are already beat down and fragile (you and your wife). You deserve better than those people. You can fight them tooth and nail and expend tremendous energy that might be better spent loving on yourself and your wife and saving what actually matters. My wife and I just DA'ed (still waiting on elders to find our letter and get their act together enough to make the formal announcement) and it is so freeing. I'm a natural fighter that doesn't go down without getting my licks in. However, I see more and more how that's just my ego trying to control things that are often out of my control. I don't know all of your history or claim to, but I hate to see you getting yourself so worked up over something that doesn't matter, as you say. It doesn't matter, so let it go. Let them go. Save your energy to fight for those things that matter and just send them a DA letter and move on. I know that a lot of people here criticize that strategy as letting them win, but I'm the one sitting here in peace and freedom while others are fighting these intense battles and going through tremendous agony to keep up something that is toxic at best.
Please take these words for what they are, my care for you even though I don't know you. I see the hurt and anger (which usually comes from pain) in your posts. I see you fighting so hard to control how this thing goes down and getting yourself worked up. Please take care of yourself first, and your wife.
Peace.
