Disclaimer: I know plenty of fathers leave, I know people are survivors of domestic abuse, I understand people have mental health issues. This is categorically not the case.
Dsd's mother left dsd and her marriage when dsd at preschool age. She to the other end of the country(she had a job locally that she left as well). She sees her monthly. She may have has mild PND but was being treated.
AIBU to not understand how she could do this? If I am BU then help me to understand these actions.
