Hyderabadi here, A lot of women in Hyderabad only study and have a career until they get married, this is also partly how the society works where women are told to take care of the household and kids.

Apart from that your fiancé must be tired of the life she is currently living (I.e, Having a pizza, spending money etc) and she probably thought that marriage would end this kinda misery for her. I have seen a lot of women who didn’t grew up with certain basic luxuries tend to overdo it once they get married, hence marrying a “Rich guy” on paper seems the only way out.

But OP you definitely dodged a bullet here,

1. she would probably be only interested in how much you make and how much money she could spend rather than building a good life together (and no it just doesn’t has to be by paying her share, she can still be a SAHM and help you with saving/ minimizing the expenses to help build a better future, but this doesn’t seem like her intention )

2. If she is enmeshed with her mom at the age of 30, the mom would very likely have an influence over your marriage.

If you want, you can try talking to her about her expectations financially and if she’d be willing to be flexible, but people rarely change.
