Tact, something you're learning at this very moment: love is always a one-sided thing. It's awesome when you love someone who also just happens to love you, but there's absolutely no forcing these things. Neither women nor the world have anything against you, this is just the way the world works when all people have free will. And though it may be painful, this state of things is also beautiful and right.
Let it go. Letting the object of one's affection exercise free will is the most wonderful act a lover can ever do for another; precisely because, at that point, the beloved is no longer an "object," but a real, respected human being.
It's easy to get angry when you've met someone you want to get to know on a much deeper level, only to find out that person does not feel that way about you. At the root of this anger often lies the attitude that there "must be something wrong with me." This is a logical fallacy imposed by societal standards, which program us to believe that if we're single, we have a big "PHAIL" suddenly tattooed on our foreheads. "Old spinster," "seedy bachelor" and all that.
You know what? Screw societal expectations in this regard. With or without that perfect soulmate, you are a full human being capable of exercising your beautiful will to whatever ends you see fit. Back straight, chin high, and move on with life.
That is what I believe. At least for now.
