im inlove with my Alien best friend

A guy and a girl can be friends. At some point ,one of them will fall maybe temporarily ,maybe at the wrong time ,maybe too late or maybe just maybe Forever.

Shakespeare said : that a boy and a girl can never be just friends

Lincoln said : friendship is the starting step for what we call love

Wordsworth said : proposing a guy or a girl for friendship is indirectly saying I Love You

Jackie chan said: love is an everlasting friendship

Michael Jackson said : that if one can be your best friend he or she can easily be your partner in life .

So I'm gonna ask you can a boy and girl can only be just friends?

Will one of them fall?

Will they become more than just friends?

Can they remain only friends?

Is it only a one sided love or not?

Will they both fall ?
