wow, I'm curious about this question myself..I believe when you love someone you will know its love by the way you feel ... I have given all my love to someone and to be honest, he is one person I believe can only love so much . There are people out there who only want to receive and not give back or should I say "they dont know how to give back"..I can't wait to see the responses to this one...alot of smart people on this sight ...they have helped me many times ...good luck and take care
