You Don't Walk In anymore

I should have kept the door close
now I opened it and
he went out
and you came in
you stay long enough to create a warm and comfort
my heart is so warm and comfort when you are there
you ask me to lock you in 
but I don't
so the door is still open
so you can walk out just as you please
and you really walk out
reaching for another door
I try to make it ok
believe that you are just common visitor
like the other
but why does my heart feel so  empty
it's empty now
and you don't walk in anymore
so now feel like I lost all
no one walk in anymore
