Searching a sad duet love song

Hi,

I was shopping the other day and heard a song, with a male and a female singer that sang different parts, it was kind of like a sad love song, seemed to be a new song, and I can kind of remember a line from the chorus "I shouldn't have called you but I was a little tipsy" something like that. If anyone has an idea what song this might be, please help me, Im desperate!

Thanks in advance!
