In relationships, offloading personal responsibility onto someone else (aka blaming another person for your choices and behaviors and thoughts and actions) is something like projection, blame-shifting, codependency.

This makes any healthy relationship impossible, as no one can be responsible for someone else's decisions and actions.

Many emotionally immature folks appeal to this and use guilt and shame to get another person to believe they are responsible for someone else's emotions & choices. It's textbook toxic.
