It doesn't sound like you messed up to me. There are always things we can do better, but isn't it normal to feel and convey resentment given what happened? You're still human! I think you can take what your friend said and use it to improve but also to be gentle with yourself knowing you've had to go through hell this past year. Regarding the schedule change, is your divorce still pending? I guess I don't know whether it'll be different after divorce when everything is written in paper or if it'll always be flexible as it is now.
