I am very happy for him. I do not know him but I think marriage  as a concept is a very productive(pun intended) institution.

Marriage leads to alliance between two people and it is stronger tham just commitments that two couples give to eacvother. Marriage makes them push to the limits sometimes by making them compromise but having a stable married life and a life long life support is very important for the menatl health of two person. Without marriage a couple when out to test by difficult times may get apart but marriage keeps them together.
