i think we all would but the problem is what we percieve true love to be. life is not hollywood and is a lot more complicated.
one true love is like chasing rainbows. we remember past loves in rose tinted glasses but if they were still with us i am sure they would piss us off somehow.
The reality is the people who are truely in love are the ones you may least suspect.
the closest definition i have of true love is my love for my child. we are not perfect people but our aspirations and dreams tend to want us to be. we have all been in love head over heels, very rarely this original love lasts and is recipricated, for the vast majority however i think we hook up and fall in love over time and sometimes fall out of love as well but it is not that crazy love we all dream about.
its a lovely idea though.
