I think the existence of reasonable precautions such as prenuptial agreements indicates that this statement is false: many people enter into a marriage with the full knowledge that it may end before the death of one of the partners (presumably contrary to their desire at the time). I think that counts as "anticipating". Only 5% of all married couples in the United States got married with a prenup. The fact that signing a prenup is so completely in everyone's interest and the fact that only 5% of marriages have them proves my point - no one is anticipating or looking forward to their own divorce. Heinlein put it well: "We always marry strangers." He was married 3 times. I'd be willing to bet he had 2 of those divorces behind him when he wrote that.
