My advice is always to seek love and develop love with the knowledge of the mortality of love, just as there is mortality in anything that is born. All things are impermanent, but all things are also inter-dependent. The love, compassion, and acceptance we develop with our spouses carries on beyond our marriages. The love we develop in our marriages is not less important because it is temporary, but more precious because of this fact. Two people who have bonded and joined their lives to journey their short time on this world together are a blessed by each other and are able to take a non-monastic path in their understanding of happiness, wisdom, understanding and compassion.
We must choose the Buddhists we wish to be develop and become, always understanding that the goal is not nirvana, but true happiness. While a married lay person must carry a heavier burden in the physical world, they still walk the Middle Path.
