I have been looking for this book for years, I read it in the early 90's. It's about a woman who has really low self esteem and she marries a doctor who's whole family are doctors but she still loves her old boyfriend who is an artist named Nick. I think the word wife may be in the title but I cant remember, the cover was a woman in a wedding dress with her back to you holding flowers I think. I remember scenes from the book but cannot find it.
