Another brilliant article - short and to the point. I think women especially see themselves too often through the lens of their relationship. It is always helpful to see yourself as an individual first and foremost and focus your energy accordingly.
I can also recommend the book "Committed" by Elizabeth Gilbert on this topic, which examines how marriage is seen in cultures worldwide. It makes it clear that in most Western cultures, we place too much emphasis on marriage and our expectations of what relationships should "do" for us are way overblown.
