Why love, if losing hurts so much

"Why love if losing hurts so much?we love to know that we are not alone,We've all had relationships that didn't work out for one reason or another,perhaps we made mistakes that drove the person away or maybe our partner treated us wrongly.The key to moving on from the end of a relationship is not to focus on what went wrong or to blame our partners for their shortcomings,rather when a relationship ends our task is to determine what lessons we can learn from the experience".
