Solved: no name, no singer

basically
i've been hearing this song on the radio a lot
but i just can't find it
i looked with lyrics
and everything
and yet i found nothing

maybe someone knows it?

it's like a duet
it goes like
man : "i love you"
girl "no you don't,"
man : "i love you"
girl "no you don't,"
man : "i love you"
girl "no you don't,"

and then
man : "i miss you"
girl "i wish you were,"
man : "i miss you"
girl "i wish you were,"
man : "i miss you"
girl "i wish you were,"
girl "all you need, is ......... .... .. against you"


the song ends with "so cut it out"

or smth, i know it's not a lot of details, but if someone knows the song, he must remmember these words ^^
thanks in advance :P
