I ask myself the same question. I don't understand why people get married because everyone seems to get tired of a partner/spouse after a certain period of time and then you have to go thru the turmoil of breaking up and starting a new life in a sense. Even family members who live under the same roof for decades and who love one another eventually get tired of one another for whatever reason it may be. Society is really built around (and stresses) being independent and if a person relies on another too much that can be unhealthy. Personally, I haven't figured it out yet. I haven't found a balance. I suppose a person needs to be very healthy in order to make a long-term relationship work well.
