If you were single on Valentine's Day and you wanted to be in a relationship , the fault may be in your beliefs and what you are projecting out. If you believe something to be true, you will find evidence to reinforce it.
Quantum physics has already showed that the scientist affects the outcome of the experiment just by what they expect to find. If you observe light as a wave, it behaves as a wave. If you observe light as a particle, it behaves as a particle.
The interaction of your observations and the filters of your perception affect everything you perceive. You, the observer, see what you expect to see. So if you believe that "all men are cheaters" or "woman only date rich men", you will find that to be true. You will find the evidence you need to make your belief true. And the cycle will continue.
And ask yourself this, if relationship are so "awful", then why do you want one? Perhaps if you focus on the things you do like, you might begin to attract something (someone) more positive.
Now I'm not saying that everyone should be in a relationship. Actually, you can learn something from your happy single friends. Simply be happy with what you do have. All too often people focus on what they don't have instead of what they do. If you are single you can enjoy being single. If you knew that in two years you would be married, you might be enjoying being single right now.
if you want to find the "right" person, first look inside of you, and find your best. The rest will follow.
