Do I believe in love? Sure. But different people look for different types of love. Romantic, sweep-me-off-my-feet love is quite rare and usually doesn't last, in my experience. The most lasting relationships tend to be based on shared experiences and values. I was looking for someone to be a companion, someone I could admire and respect, and who valued me as a person. And a great butt. I found him.
Hint: The people you meet in a bar tend to like to hang out in bars. The people you meet at the roller derby tend to like to hang out at roller derbies. Wherever you like to hang out, whatever you like to do, is where you are more likely to find a companion.
As for the booty calls, if you're not after that, don't waste your time. There are plenty of other guys they can call, and somewhere out there is a guy who would LOVE to share your life with you. So, do you know what you want, what you like, what you admire and respect? Can you recogmize it when you see it?
Don't wait for love to start living your life, though. After all, you'll want to bring something to the picnic.
