Looking for song I heard today 5-5-10

I work there, and i still get stumped for songs when I cant make it to the back room to find out who sings them.

this one has a background that goes something like da da da dadada da da

and then its a female singing something that sounds like "two months is not enough" and then i wrote down some more of the the lyrics

"and its a lifetime cuz i need him, so id give it all away just to have him here with me"

ive tried searching these lyrics but I am getting nothing >_<

"so what" by pink??
