Not that you should stay in either cases.
A toxic relationship implies responsibility on both sides. An abusive one side. (I know there are 2 people in an abusive relationship).
When I was in court the judge said one time “we” were in a toxic relationship not that “I” was in an abusive one. Then went on to say he had abusive behaviours and denied contact with dc. Toxic implies blame on both sides doesn’t it. Victim blaming.
