In truth neither.
Being married means being in a "partnership" ... There will be times when the wife will bend to the husband and there are times the husband bends to the wife.
In reality partners talk about things and explain their individual points of view. If your partner is making more sense than you are you listen to them. If they are not you expect them to listen to you.
If you both make sense and neither wishes to bend then you have to work out a middle ground or agree to disagree on this area.
There is no one person who is the decision maker in most relationships. Unless of course you have chosen a very submissive partner.
