Yep I had a tough time accepting one person could make a decision for 4. What has helped me immensely is understanding that my ex is not a horrible person she is just trying to be happy. She has one life to live and should be able to live it her way. I wouldn’t want her to stay if she’s unhappy. I have friends who are staying married for the kids and their lives are horrible. You’ll get there it just takes time.
