Staying with (undergoing) an abusive partner is not being stupid. There are those who claim that. Because you easily get the psychopaths out, they say.

I say this: accepting abuse is a pair of pincers that you cannot get out of with your mind if your mental strength does not follow. This has nothing to do with being stupid, just that because of your mental state your mind ignores the red flags you see. As if our mind works in isolation from all other aspects of our lives.
