help me understand

i need some help
maybe some advise
this pain being felt
is from all your lies
somebody just help me understand
why you don't need me
why im not part of your plan

infact i never was
i could never hold you to tight
or say you were mine
you've been out of my sight
its like im standing in line
and of course im in last place
but you don't even care
i can see it in your face

i wish i can just let go
but i've never had to do this before
let go of someone who touched me so
i know in my heart you don't need me anymore
and i keep thinking who's goin to hold me tonight
when im feeling lonley
with all the things we got
i just can't understand
how love just stopped
some say love
will tear you up
some say you
were a waste of my tears
a waste of a year
and what i fear
is that they were right
but now i know better
im stronger than ever
and will get over you
your now a memory
just a guy in my past
you join the rest who couldn't last
now your with a new girl
she's now part of your plan
i just wish someone
could help me understand
