Should I reject this prospect as he wants a working woman?

My family received an interest from another - they are seeking an "ambitious woman", and are "willing to support her career". I am working currently, but I am not ambitious. I will quit sometime after marriage if my responsibilities increase too much. The thing is that this family is quite well off compared to us, and my parents are totally in favor of them because even the horoscopes match. Should I reject? What do you guys mean when you say you want to marry a working woman? 1. Is it so that she can contribute to expenses? 2. Does she have to work throughout, or are you okay with her quitting after having children?
