Im over you (i think)

I'm sorry but I'm over you
and i know that you feel the same way too
i never thought this would happen, when you would go out with my "best friend"
but I'm just confused because i thought that we would never end
you said that you loved me and now you love her
i never thought I'd see the day that you made me suffer
but as long as she's happy I'm happy too
i hope you guys last longer then me and you
