In the beginning things are different because they're new and exciting. Every day you learn more and more about your partner and things they do surprise you. As you progress through your relationship that "new" excitement fades and you're left with the relationship that you created. Being married, being inlove and having a positive and good relationship are a choice to a certain extent. You choose daily what battles to fight and which to let go. You choose to put effort into your relationship, or not. Its a choice all the way not a right or divine intervention. Alot of divorces (although not all by any means) happen because people give up and choose not to fight for their relationship. Personally some of the initial excitement has passed for my FI and I as well, but he is my best friend and the only person I would ever want to be with. We have our issues, but we work at them every day, and are commited to making our wedding and relationship work. That's my 2 cents
