I am going to get a lot of flak for this. But the more I read things like these, the more I feel marriage is not for everyone and society has a whole should stop gushing down this concept to next generation. Personally I feel, If you have to write a note to your spouse everyday to "save your marriage", then you probably didnt have one to begin with.
But it turns out that marriage is really just a partnership and relationship, and all different kinds of people have different styles and interpretations of what that is and how it works for them. Some people need a lot of passion, some people need a lot of stability, some may need both, or neither.
But there is definitely something to the notion that good relationships don't come easy. People are all flawed in different ways, and sometimes people need help to work through those flaws in order to have successful relationships. Plus, a marriage may involve some long term expensive investments, like a mortgage, pets, children. So "saving your marriage" might actually be quite a rational and emotionally intelligent act, if all partners are amenable to it. Best-case scenario: you end up with a long-term loving partnership and a wonderful life; worst-case, you don't. Seems like it's worth saving?
