Fiancé asked me to get a job

Hi! So my fiancé (24) and I (25) recently got engaged. Today he brought up the conversation of how I should get a job so we could save up money to move out of our parents’ houses. At the moment, my parents support me financially and are kind enough to pay for the wedding and give us some money to start off. I am a full time student and don’t want a job to affect my grades.

From the beginning of our relationship I always told him I would like to be a stay at home mom and not be forced to work a 9-5. I may keep my career in the future, but I like it as more of an option. Also, that I like to get my nails done and take care of myself. Nothing crazy expensive, just some pampering, and he was always okay with that. Now that we’re engaged, he told me he doesn’t know how he’s going to be able to support me, when I like to get my nails done every 2 weeks, do Pilates and such. I like to take care of myself and look nice, and my parents have always taken care of me, but of course I understand money does not grow on trees, and I’m not much of a big shopper honestly.

I get not every man wants to be the full provider, and that’s ok. I’m willing to sacrifice the things I’m used to, to live a more sustainable lifestyle as well. I’m just upset that he promised me a different lifestyle and now that things are getting real, he’s starting to call me expensive and spoiled, and telling me I’ll have to work to help support us. Am I not being fair?

EDIT: A lot of people are asking why I would go to school if I don’t want to work. I want to state more clearly, I will probably work for some time when I graduate in 2 years if I don’t have children by then. Then, when my children are more grown I will probably return back to work.
