Dealing with the schedule. If she doesn't have the job yet, then ignore her request to discuss it. Second, if her new schedule doesn't work with yours and you'll already have a custody agreement in place, I would just rely on that.
What happened with your daughter, next time if you see that, calmly walk up to your WW and say, "this is neither the time or place for this". Take your daughter walk her to the car, and tell them, "I will be right back". Then, discipline your WW, something to the effect of, "I understand what our daughter said was hurtful, but you are her parent and an adult, under no instances should you treat her that way". And walk away, your job is not to comfort her no more. She has made her decisions, it's time for her to live with them. Your actions in this moment is important. First, it shows your daughter, that you will protect and you love her, no matter what (girls need to see their father protect them). Second, it shows your WW, that you will protect your kids, and you are not going to just allow her to act any way she wants.
Lastly, Don't be yourself up. Your were taking care of your family (what a man is suppose to do). Your WW took you for granted. It's her lost and your need to start acting like it. You don't have to pick her back up every time she falls (She's humpy dumpty and she's on her wall, stop waiting for her too fall). She has fired you from that job. If you got fired from a job, would you go back trying to ensure that job was still being taken care of, or would you look for another job and then start focusing on your new job. I bet you would start focusing on your new job. That new job you need to focus on now is, YOU and your kids! You are special and worth more than the universe can spend.
You will have down days, you will faulter, but just remember to get back up. Healing is=giving up the ability to change the past. You can't change the past so stop trying!!!
Onward and forward.
