I am blind,
I can be true or false,
I can make grown men weep,
I can make relationships stronger or cause them to crumble.
I can be wanted, or not .
I know no boundaries,
I am the foundation of life,
I can be cruel,
I strike when I will,
I often leave you no choice,
I can conquer all,
I bring great happiness... and great sadness
Who am I?
