theoretical, you may want to put a trigger icon for your thread here. It has the potential to be triggering for "some" members.
You are right though, some recent threads are touching on how individuals get brainwashed and stay in abusive relationships because they do not know what else to do. However, a lot of times it's something they witnessed take place in their parents when growing up. So often what is considered emotional abuse and controlling techniques are "familiar" to the point where often a person picks a partner that has similar control or toxic issues unknowingly.
