I'm one of those people who believe that to have a happy marriage, you have to work at it.
I have been married for almost 15 years, and my marriage, like all the happy marriages I know, has required work - sometimes marriage is very easy, and sometimes it's a little more difficult.
I have found working through the rough spots in my marriage HAS been hard - but it is very rewarding. My husband is happy, and I am happy, most of the time.
