holding on? or letting go?

just a thought to ponder on..

how can you express to the one you love that you really are in-love with him/her?

is it by holding on to the love you have and fighting for the foundation that you have built? letting the person realize that no one else can love him/her the way you did and still do? insisting that you stick around even if he/she does not want you anymore just to prove how much you love the person?

or is it the other way around and letting go of that person as soon as he/she tells you that he/she no longer needs and wants you? setting the person free even if it kills you just because his/her happiness would also eventually make you happy? saying goodbye to him/her even if it means losing the one person you truly love simply because that is what he/she desires?
