Should I just give up?

I've been looking for a relationship but apparently no one is interested in someone who doesn't want kids and doesn't want to get married. A friend of my told me that If I don't want those things then I'm going to find it hard to find any one..., so is it a waste of my time to keep looking? I not about to go out looking for someone and get married and have kids just so that I can have someone. So, should I just give up the search?
