i don't want to sound like an idealist, but once you start to calculate these probabilities and/or think economically,your love is not love- it's just a hallucination, so i would say those guys/gals to WAKE UP and move on with your life :P i believe in people who don't do things just for the sake of doing. "i have a gf/bf coz i want to look and sound cool" --that's crap! YOU EITHER DON"T DO IT, OR IF YOU DO IT, DO IT WITH PASSION. if you are passionate about ur love, if you believe in it eternally, then all these arithmetical interpretations sound like bull. LooTe
