Soul Mates?

Do you believe in soul mates? Someone that is more than someone one you love unconditionally? But someone that changes you? Makes you want to wake up and be a better person, someone that opens your eyes to something that you have been blind to? I used to, and I think I still do in some ways. But I think I'm destined to be alone, never to have the family that I dreamed of one day having, but rather be alone and a mother only to my pet. Happiness isn't something that I'm going to be lucky enough hold on to.
The man I love is really gone, and in his place a man that thinks that he is a playboy. Man-child is more like it, he's an arrogant ass that thinks he's hot shit now.....and I hate him when he is like that. Where there was once warmth and goodness is now coldness and anger. He can love for an hour maybe two, and in that time his love is amazing, but then there is another and another and the love that was once so welcoming becomes the most hurtful.
So soul mates....they exist for everyone but myself. Mine has come and gone to be another man, and perhaps a soul mate for another woman who isn't myself.
