I am sorry for your loss. That's a tough road to walk. But from what I can see, you are a great dad and you can have a different relationship with your own boys. You already are and some of that credit goes to your W. Something to be thankful for in all of this
As for the rest of it? You are on a slippery slope if you start thinking about what she is or is not doing. You may be right, but you also may be wrong.
Like I said, I walked you in your shoes. I wouldn't trade places with my ex for all the tea in China. I know that's hard to see right now, but believe me she is not somebody to be like. If you keep ruminating like that, you'll get there in a hurry.
Be thankful for what you do have right now. I know it's not easy to watch the trainwreck nor to take the BS. But stay the course. You'll be glad you did. Trust me. It's a long road but it is one you are walking and one you can walk. You are able and you are strong enough to do it. And you'll be the great dad and husband you are along the way.
And may you know God's peace tonight.
