I am glad that you posted the second post because after I read your first post I was thinking you were a lost cause. I am baffled why you continue to try to use logic and reason knowing that you are just pushing her further away.
Then by telling her that you are only going to speak with her regarding the kids just reinforces to her that the changes you made are not real and only a ploy to get her back. I am not saying you should be friends with her in the future but what is the point of telling her that now. It sounds petty and desperate.
Have you read the lighthouse story? That should be your focus. Keep a clear path paved home. There is zero reasons to burn any bridges right now.
IMO you are no where ready to date. You have a ton of worked to do to insure you are prepared for your next relationship. Focus on you and the kids and what kind of life you want to build for yourself.
