MCA i'm having doubts with my GF due to very different financial values

I am currently earning more than 3x what my Girlfriend is earning. Ang pinagkaiba lang is breadwinner ako, sya naman is from a well off family. They are so well off in fact na dahil nahihirapan syang mag commute the past few weeks, her parents bought her a car.. just like that. Ako naman even if I'm earning way more, i make sure to save as much as i could, spend as little as i can, and provide for my parents. Alam ni girlfriend ang sahod ko and pag nag dadate kami, almost never ko naman sya pinagastos. However, sobrang baffled nya when I say na wala akong pera dahil malaki naman daw sahod ko. Bakit daw luma lahat ng damit ko. Now, my girlfriend is an angel. She would never hurt me. Pero our values when it comes to money is so different talaga.

I tried opening up about it but she would just usually brush it off and joke na gusto lang nya maging house wife, wala syang plans, ayaw nya mag trabaho. I'm starting to think na hindi na sila joke. She would rant day in, day out about her job which is okay but when I do the same na very madalang lang, she get's upset. She is in an entry level position mind you and I am a senior manager so the scope of responsibility is very different.

Worried lang ako na since she's used to getting what she wants, when she want them eh baka yun din ang expectation nya pag kasal na kami so I am starting to rethink our relationship.
