My parents have gotten divorced, and since then, I have found out the kind of man my father really is. He's completely abandoned me with no regrets, and it hurts, but I can't tell anyone in my family because they tell me to think about how my mother feels.
Your pain is valid. Don't let others invalidate you and especially do not let others mistreat you. When that we love do not care for us, we must work to care for ourselves.
