Destiny, Soul Mates, and all that Nonsense

How do you know if someone is worth it? How do you know if you are supposed to be with someone or not? Is it the way they look at you? The way they make you feel? The touch of their hand against your skin? The way the silence can become so comfortable that neither of you need to say a thing?
I'm having a really hard time with this because I am just now accepting the fact that I don't believe in soul mates, destiny, or fate. I used to think that everything happened for a reason. Things fell apart so that other things could fall together. One door closed so another door could open. All these cliche attempts at trying to explain away the fact that my life didn't turn out the way I expected. Don't get me wrong, I love my life. My life is full of amazing people and experiences that I wouldn't trade for the world. Yet, there's something missing. When I get off work, I come home to an empty house. I sleep alone, I wake up alone, and I eat alone. When I have good news, I call my best friend and she and I squeal and talk and then I'm alone in my thoughts again.
I used to believe that there was someone for everyone. That someday I would wake up and meet my soul mate, the person whom I was destined to be with for the rest of my life. I thought that fate would make sure that the decisions we made would lead us to each other. Maybe I decided to move jobs and the person who delivered the mail would end up being my forever. I believed in "magic" because so many people out there had found that perfect person, so I was destined to as well, right?
Wrong. If that was the case, no one would die alone, unloved. Everyone would be happy with someone that MADE them happy. There is no such thing as soul mates, destiny, or fate. Yes, some people get lucky and find someone amazing to share their life with. But for the most part, people settle. We decide that we're happy enough. Things are good enough. We deal with it.
I don't want to settle. I may not have a destined mate out there for me, but I refuse to settle for less than I deserve. When I'm with someone, I want to feel like I am the only girl in the world, the only woman they have ever wanted. I want to feel as though I am amazingly beautiful, despite my flaws. I want to feel intelligent, hilarious, and unbelievably good in bed. I want them to WANT to spend time with me, to be their top priority, or at least somewhere near the top. I don't want to have to beg for them to hang out with me. I want to feel important, cared about, and cared for. I want my thoughts, opinions, and feelings to be taken into account when they are making big decisions. I want them to accept me as a person and never ask me to change even the slightest thing about ME. The more I think about it, the more I have answered my own question. How do I know? Well, if I don't feel all those things then they aren't worth it. And honestly, I haven't felt that in a long, long time.
