Trust issues

What am i supposed to do?
i've messed it all up
all i've got is you
you see this as a chance
to walk all over me
because i'm down so low
i can barely see

i wonder if u love me
if u really care
were u even truthful
when you said you'll always be there

i know i shouldn't question this
but i just can't understand
what happened to our relationship
things have gotten outta hand
