It all comes down to ( for young children) that your parent would rather spend time with some one else than you.
Think about it most kids of divorce would see the parent that left what every other weekend with the options of an extra day a week, mean while that parent is spending most of his or her time with the person they left the marriage for.
Young kids don't understand, even teens get resentful of having to leave their friends to go visit the other parent.
Plus having a parent in your life that is so toxic is a no win game, most kids feel to guilty to cut them out of their lives, and more than likely pick up some traits from that toxic parent because they don't know any better and it's becomes a coping mechanism, only to affect their future relationships.
