There's no answer to this question.
Well at least you set up the thread with lots of places for it to go.
that was good. +5
how can you be happy? let's see... well, your sexuality shouldn't be the only thing contributing to your happiness. neither should love. I realize that many people live their life and make decisions that revolve around romantic love. personally, I don't feel that love--coming from a husband or wife, whoever they may be--is the sole proprietor of your happiness.
love comes in many different forms, be it friends or family. as long as you have the love of those people... then you're set. your sexuality doesn't define you, though it is a definite part of your being.
find yourself a stable job that you enjoy. drink good wine. travel. meet interesting people, and become an interesting person. treat your parents nicely. stay in touch with your siblings. dance around your apartment/house/shack naked. smoke a blunt. get in touch with some spirituality, be it god or simply the forces of the universe.
these things I've listed above... that's what makes a happy life. not whether or not you can come out of the closet. and unless you are arranged to be married, which I doubt you are, I see no reason for you to be forced by circumstances to be partnered with a woman if you're gay.
put aside romantic love and your sexuality and find other ways to be happy. that's my answer. despite the fact that you already insisted there wasn't one.
