You said it yourself you ' confronted' the issues as you saw them.
Some people are clued up financially and some people aren't, some people value money and some don't. If she is one of those people who simply consider money to be of secondary importance to how someone else feels, or the love within a relationship then you will have hurt her far more deeply than you can imagine. I don't personally feel, with the limited information you have provided, that she is ' spoiled' or used to her own way at all, just rather that you totally pulled the rug from under her by placing more importance on financial matters than on her happiness, when she perhaps is someone who would never have done that were the situation reversed.
Imho I think it's to be expected that she now keeps something of herself back as you have trashed her fairytale idea of you, for her now it's a trust issue and she won't be trusting her own judgement about anything for a long time including how reliable as a partner you are.
I'm sorry to sound so negative towards you, but I think under the circumstances it's all pretty much to be expected as in her mind you have placed a financial sum on her love for you, and to her her money now seems of more worth to you than her precious love. This will take some getting over and your are in her court now, only she can establish how long if at all.
You sound pretty irritated by her, I imagine she's also picking up on that, which probably won't help either. Try a really good sit down ( which she'll resist as last time it ended in her world falling apart) and try to focus on how much you care for her, not what you perceive she's doing wrong or isn't paying for, I think at this point it's the only thing you can do.
