She wants this divorce. Any thoughts on if I should resist or try to slow it down or fight it?
I feel like if you truly love her as much as you say, then you will let this divorce go through at the speed she pushes for. I wouldnt help speed or slow the process.
You have already gone down this road once so nothing you say or do can be believed by her right now. I would stop focusing on her and OM. Use this time to truly focus on you and your kids and become the best InFocus that you can. Really look into your addictive personality and figure out who you are and who you want to be. Then start living as that person. If it turns out that you rekindle at some point in the future, then great.
But I would say to set her free to live her life. That way you can focus on what you need to stop making the same mistakes.
