I think what alot of people realise is that after the thrill is gone if you want the relationship to continue you actually need to work at it. Work to know them as a person, a seperate entity from you. Work t share your life with them and vice versa. It works both ways. My friends are at an age where they are all beginning to marry (I am 26, married for three, together for 9) and I have said the same thing to each and every one of them: Communication is the key! Talk about problems, talk about thoughts and dreams. Where you see your life going and work towards the common goals and support eachother in their dreams..
