Who is a better half? and why are they given the title of better half?
Someone who shares your life with you? Someone who shares your happiness with you? Someone to shares your sorrows?
I would say, someone who is part of you. That special someone who can complete your incomplete sentences. Who can make you laugh, sing, cry, the one who breathes life into your body and purifies your soul.
Look for that someone who can understand your tantrums and your anger.
Happy searching for your better half.
