depends. If by partnership you mean husband and wife devoted to form the strongest union they can together with complimentary strengths and having each others back to get through weaknesses or other challenges, yes.

That said, I do believe that there needs to be an ultimate deciderer when options arise and no immediate consensus or persuasion can set forth a plan of action. That role, while traditionally always patriarchical or matriarchical, doesnt need to be, but those getting married should discuss this beforehand.
