So many times...
People spends almost their whole lives finding the RIGHT person to complete their lives.
For those people who already founded their better half, you should know how lucky you are, so keep them ,take care of them and keep the relationship for eternity.
For those who have not founded yet ,just live your life. Do not afraid of falling in love, hurting is just a part of the way to found TRUE love.
Someday somehow...
True love will be yours...
