I can't believe it comes to this

I can't believe your here
I can't believe it comes to this
I can't believe you hate me
because he dumped you
you'll probably get over it
in a few days
you'll probably be over it
the next time we meet
you barely even knew him
you two dated for two weeks
two days before the end
you started crushing on his best friend
you only knew him through me
and I told you not to go out with him
but you never listen to me
it's funny really,
how your two worlds collided
but not for long
the deed is done
and I'm stuck in the middle
at least he doesn't blame me
at least he doesn't avoid me
when I'm around you
like some people do(specifically you)
Why is it he and I can be friends?
Why can't me and you?
