If a man wants a good marriage, then it is only logical to consult his wife/wives on such matters. If a man does not want a good marriage, then let the man drown in his own arrogance.
With the above being said, in Islam, a husband does not need permission of his wife/wives for marriage, this is a man's right as dictated in the Quran. This right comes with hefty responsibilities though, hence treat them all equally. That means if you buy one a car, then you buy all of them a car. This is not negotiable. This also includes love, there aren't many men out there who would be able to maintain that perfect balance.
Today I have seen many cases where a man has one wife in Europe, one in America, and one in Asia. The man stays with one in America, and completely neglects the rest. This is wrong as it breaks the condition which allows men to have more than one wife to begin with.
