No, because love is not only an impulse it is also a decision .
It is a conscious decision to not pursue an attraction, a
self-discipline not to put oneself in potentially compromising
situations, a commitment to stay faithful, an effort to nurture the
love in a relationship. Sounds like work leh.
That aside, I don't see why a short-lived relationship, if genuine
and true while it lasted, should be of any less value than one that
lasts for years on end. Is a flower that blooms for only a few
hours in its lifespan any less precious than a perennially blooming
plant ?
