It seems that a husband is obligated to make his wife happy. Meaning without him she wouldn’t be happy.
I don’t understand how your conclusion here follows from your premise.
I have a mitzvah to give tzedaka and feed the poor. But that doesn’t mean that if I don’t do it, the poor will go hungry. Yes, they might, but it’s certainly not a foregone conclusion.
I have an obligation to make my wife happy, but that doesn’t mean that it’s impossible that she might find happiness without me.
