Should I go for her or not ?

Okay long long story short when i was younger i hung out with this girl for like 5 years trying to get her to date me and she ended up hooking up with one of my friends a few years later she calls me one night drunk as hell and comes over and tries to have i feelt awkward cuz she was so drunk that i didnt want our first time to be like some drunken thing for her i started talking to her friend a bunch who i was friends with in highschool and we hooked up a few times then her and her friend became like enemies an dont talk now because of me anyways so recently me and the girl i was crushin on for the longest time went out on a date in the city and it was perfect me and her always laugh together an joke around and its awesome being with her however i see she is way into fashion to a point wereso its disgusting shes always asking her dad for money for like 500 dollar purses and shes always gettin new cars every like 2 years and she always makes fun of other people for not being fashionable or poor its just shallow...Now im hittin the age where im looking to marry and she is the only one i feel i can marry however her love for money and fashion is keeping me away partly in fear i wont be able to provide the lifestyle she would like. I have confirmed that she does like me now a lot and shes super hot its just I dont know if i wanna spend the rest of my life busting my *** at work to pay for her stuff thats so expensive ie 500 dolalr purses 50 thousand dollar mercedes etc etc .....so should i go for her or wait for someone else keep in mind im looking for someone to marry not just a hook up
