Random thoughts.
Being alone is the most untolerable human condition. You can live with 14 people and feel alone. You can be married and feel alone. You can live a million miles from anyone and not feel alone if you have some way to communicate with people.
People change, grow if you will. The reason many marriages don't last longer is the people change in different directions and no longer have common interests or goals, Nobodys fault, just is.
Personally, a successful marriage is one that begins and ends, amicably. To be able to honestly say "It was good while it lasted" and "We're still friends" is all anyone could ask from a marriage.
