We are not soulmates because our hands intertwine perfectly or because our kisses are like fireworks. We are not soulmates because we never argue or fight. We are not soulmates because we hold each other perfectly or understand each other without speaking. We are not soulmates because of any of those things. But we are soulmates for sure. Because even when we argue or fight, we will never ever give up on each other. Soulmates don’t have to be perfect. They just have to hold on, and never let go.
