I think some people definitely find someone that they want to be with and they put the work in to keep their love alive. But are they meant to be? Destined? Maybe, maybe they're just lucky. I sure haven't met mine and find it improbable that it exists for me.
After being single at a certain age, you start to understand it's not a dream. A lot of people suck and you're lucky if you can even find a friend.
