Agree, but it's more than tolerate.... we are actively drawn to, and actually attract the same damaged personality profile we encountered in childhood.
Eg with an abusive/explosive parent, we grow up learning that this is love, so we recognize and are drawn to that in others. (We may read a softer more accommodating life as weak). Psychologists also say that subconsciously we see it as a chance to reinvent our sad childhood, by being with someone similar but hopefully getting a different result.
It doesn't need to be abusive.... We are also drawn to people we feel allow themselves emotions we don't, in the hope that we will get to have those emotions close, and even absorb them. (Eg I am a selfless pleaser/passifier... so I can be inspired by this person brimming with confidence who says what they want and lets themselves feel anger sometimes,). Sometimes this can end positively, with both partners absorbing the emotional map of the other and each becoming more balanced. But just as likely it becomes more and more polarized, each displaying their tendencies in the extreme.
In just the same way, the other person will seek out and 'map' to you. So eg a narcissist who had a loving, caring, accommodating mother who he dominated, will absolutely (consciously or unconsciously) seek someone they can dominate....
