Yeah i think it's a stupid concept. It's basically a premise of weakness. You want to be with someone but you don't try and show them. Obviously if the feelings aren't reciprocated, or somehow acknowledged in a kindred manner then that person is not for you. Honesty is a virtue, and if you're honest with yourself, and the person that you have feelings for, then you'll come to a conclusion. Settling for anything that's less than what you feel you need, is ridiculous to me. Life is to short blah blah blah.
This is just my opinion, i have very little experience in these matters.... However, i don't think, from what i've experienced in life, i would do this to myself.
