I need some help for a fanfic I have started.

Does anyone remember the name of the woman that Genma was 
dating before he married Ranma's mother.  I know that she was part of 
the first season anime but I don't own those tapes.  Genma has a 
flashback and tells Ranma about her.  We she him telling her he has 
found someone prettier, richer, etc.

Also I need some help on two Japanesse words.  Does anyone know 
the words for

1.  Forgotton one
2. Revenge

I am working on a fic where Genma gets his.  No way he can put this 
off on Ranma.

Thanks
