How do we know

How do we know this is what we want
how do we know this is how it should be
we are supposed to be in love
but you always fail to show
when its Ur plan you fail and also mine too
how do we know that we are in love
how do i know you don't love her
its been a year
that since i fell in love with you
its been awhile since she got in the way
how do we know that we will last
how do we know that we wont
i love you
and you love me
but how do we know that this love is meant to be
