I always looked at it like he was emotionally abusing at all times. But I’ve been thinking lately and it appears that your emotional reaction to something they have created is what they are looking for.
So they build up something within themselves then attack by making you react emotionally and it makes them feel better temporarily.
There lack of emotion means they don’t care about what they do or say to get your reaction. They only care about feeling better themselves. There is something they feel bad about themselves and they can’t fix it so need you to.
All the other stuff they do is to destroy your self esteem and escape so they can keep you so they can keep using you?
Does this sound right?
