I think it's very easy for us to mistake familiarity for control in these situations. From a developmental perspective, when we live with constant abuse as children, our minds learn to process and understand the world in the context of constant threat and danger. Our developing minds literally take on board these abusive environments and all of the negative destructive feedback and input, and they integrate this into the fabric of the meaning of life, and it becomes your internal reality.
As we grow up and move away from those abusive situations, we often find ourselves in a world that is no longer abusive and that may in fact be supportive, safe and nurturing. And we have no idea how to live in or interpret that world! My T explains this in terms of neural pathways, the connecting mechanisms within our brains that link observation to experience to understanding and interpretation, and they run along tracks that are familiar and which have been reinforced. Where there is no precedent or learned association, such as in the face of positive and affirming feedback or input, we feel lost, confused, alien and desperate to seek familiarity. This inevitably leads to situations where we are inclined to seek out old destructive patterns, or to feel oddly comfortable and safe when surrounded by them, even if the adult cognitions are telling us that it's bad.
And so in that sense, it makes perfect sense to feel "normal" and comfortable in the company of abusers. This allows the deeply ingrained neural pathways to fire in a way that is familiar.
That's why "healing", in whatever form that takes, can be so traumatic and confusing and even negative-feeling in the short term. Rewiring your brain is no small task, but until or unless we go there, good things will never feel good or normal, and we'll never really be able to challenge or step away from the negative learned behaviours and being states of the past.
