What Is A Soulmate? It's like a best friend but more. It's that one person that knows you better than anyone else. Someone who makes you a better person, actually...they don't make you a better person, you do that yourself. They inspire you. A soulmate is someone who you carry with you forever. The person who knew you and accepted you, before anyone else did. Or when no one else would. And no matter what happens, you will always love them. And nothing could ever change that.
