Personally speaking, my oldest two children were subjected to parents I feel belittled and betrayed me and I came to realize, as my children grew older, they were being subjected to the same manipulations and other emotional abuses as I once had. When I walked away from a situation I felt was toxic to protect myself, that meant also protecting my children.
Would you hand over your children to someone you felt had abused you in some manner? Of course not. So just because one’s abusers is their parents doesn’t mean it’s okay to subject them to toxic, dangerous people. As a matter of fact, doing so is a form of abuse in and of itself.
