I should clarify about the love part.
I would equate it to Stockholm Syndrome. I guess its like pets. They don’t have anywhere else to turn :(
Edit: fawning is probably the closest to the answer I was looking for
fight, flight, freeze and FAWN are reactions to trauma / abuse. If a parent is abusing a child, children don’t really have any other immediate option other than to fawn. They don’t know to call the police, they can’t fight back or run away.
