Northern Soul/Motown Song

[troot28]

Please help - I can't get this song out of my head - but i can't remember who it's by or what it's called.
It's a girl group and the chorus includes the the lines "..... if he met someone new, if I ever lose his love, I don't know what I'd do"

Thanks in advance

doesn't quite match what you wrote, but is it this?

Yes, I'd have said the same as you mushroom - I've still got that album!
