MtnTime2896 I had not realized you are actually still young yet. I wanted to help you understand that the way your father failed you and still fails you is not your fault, never meant you or your sister did not deserve to be loved and respected AND from what you have shared of yourself YOU tend to be a caring person which can make it even harder to understand how another person doesn't care.
It's very unfortunate but that's how some parents are and they genuinely don't know HOW to be a healthy parent AT ALL. It could even be that they themselves were abused or neglected so they never saw or experienced what it's like to have healthy caring parenting. I am very sorry, you deserved better and still do and I hope you have found a way to distance from this toxic parent/father.
