That was really good! Try breaking it into stanzas, because it makes it easy to read.... For example:

I saw a new kid walk through the door
pain from his mom haunted before
he felt as if he life was a mistake,
so i heard him cry some more

then he met me and
we became unseen....
we talked and walked
and walked and talked
but no one seemed to care.

the day his mom became to care
the things that were said for joy.
we became closer and closer
untill no one came stop us.

we became boyfriend and girlfriend,
we as one became 2 again.
we tried to come back
but the pain came again

our relationship was ruined
but our friendship stayed tuned,
it touched my heart that
we truly cared about each other,

he cared more about me
then the earth itself...
he became in style,
i became in denile...

we stayed in touch through Int. school,
but after that everything was not cool

The flow could be better! i think this poem was very well done could be a bit diffrent or add more but it was still and enjoyable read

Very very very good
