Why do we bother with relationships?

"Why do we bother with relationships? Neuropsychiatrists say that we are hardwired to crave intimate connections. We long for love. Of course the reality is it usually ends in heartache. Leaving our delicate psyches bruised if not completely shattered. Why do we even bother playing those odds? I guess because we only have to get it right once. And when it’s right, you know it. Even the memory of the fulfilling relationship can sustain us; and remind us that, although we may be down at this particular moment, we’re never truly alone."
