I believe that arguing can be healthy because it means that there is communication between the two of you. If you are both communicating openly there are bound to be some issues you don't agree on. Arguing doesn't have to mean raising voices and going to bed upset. If you are both communicating about things, talking about feelings, trying to make things work, then there is no problem.

I know it is hard to trust you "what is right" meter when you grew up in a house where fighting, yelling and name calling is the norm. I am the same way. But try not to find ways to fix something that isn't broken.
