I have only been married for a year also, and what makes it work for is that my husband is not a selfish person, and he is willing to put up with my occasional dramatic moments.  I think talking is the key.  Before we got married we had been together for 2 years, and I told him the things that make me a difficult person to deal with, and how he should act in my moments of crises.  He said okay, I love you, I'll do that.  After we got married things only got better.  
Another thing that makes things work for is that we are each other's best friend, and I don't mean that as a cliche.  Really, since we both graduated, we don't have any proper friends in the area, so we hang out together in all our spare time.  All our friends are, and always were mutual anyway.  He doesn't have his "guy friends," and neither do I have my "chick friends."  We're like a package deal.  You want me? you will get him too.  It's the same other way around.  
Both our parents are still happily married, but in our situation, we learn from their mistakes, because may God forbid it, we don't want to be like them.  And, I know we won't
