Help!

My husband & I have been discussing baby names for our future baby boy.. His first name is (Santos) & he wants that to be our babies middle name because of his grandpa that passed away that also had that name. The only problem is that I don't like that name at all & it doesn't go with any of the first names that I want... I don't know whether I should deal with it for the rest of my life because it means so much to him, or just tell him NO WAY. I don't want to be a horrible wife but I don't want to name my baby a name I don't like :( what should I do???
