Keep documentation regarding how she does not show responsibility as a parent. Being late, missing app'ts, etc. If most of your boundaries for her can show a Judge that you have your boys' best interest at heart....that would help you in a custody hearing.
Whenever she tries to "cake eat"....call her out on it.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
