It's an older song, maybe middle 90's.

All I know is that a girl sings it, and the lyrics go something like this "one world, one life (lie?), I lost (loved?) the only one, ...., (after all we have been through?),..., when we cried, when we laughed (laid?)..." or something like that. Also, there is a piano playing afterward, kindda sad melody.

If someone knows what song this might be, I would really appreciate it. Thanks in advance.
