I have a song to find

I don't know of this song, but I have a song to find of my own! It's a guy and a girl singing, heard it last night in Kohl's. some of the lyrics were "and I'll never change my mind, I want to feel like this for the rest of my life..?" something along those lines. HELP?! I heard it in the juniors section. It was by a girl and a guy and kind of slow-ish!
