I'm in a classic dilemma--I am close friends with a girl, and I want to make her happy. Unfortunately, there's another guy who makes her happy, and he might have better chances of being with the girl than I. Therefore, I'm in a love triangle. Me and the girl have gotten close within 2 years, but only as friends... I wish I could push our friendship to the next level as intimates, by becoming the one guy that makes her happiest.

I don't know whether to let it go and let the other guy fulfill the role, or to fight back and be "him". In the end, it's her happiness that matters most to me...

Any advice? =/
