Indeed marriage as I see it can lead to as much pain and suffering as the happiness received when two people come together. The future in general leads into the unknown, where we may suffer great amounts, whether it may be a death of a love one or just trying to survive in life. Whether or not the rest of this quote is true or not is up to you, because I could care less about what other people decide to do. Regardless marriage and the future can both lead to plenty of painful experiences that one can suffer throughout their life. Life is hard and whether or not we make it harder than it looks is up to us by how we put our efforts into our lives.
