I agree with Zewp, Winner has actually started to think this through, and is on the right path. Winner, the only single mistake you made, was asking for relationship advice on mybb. It is one thing to ask advice on what to do with your finances on here, but completely something else to ask about relationship advice on here.
That said, I personally believe you should talk with here about it. One of the foundations of a ever lasting relationship, is that no subject is taboo to talk about.
The second important aspect to keep in mind is, while the man is usually the logical thinker in a relationship, you shouldn't be the one that solve her problems, that will only make her, like you less, and could eventually be the start of spiraling down into a relationship that will break up. Keep doing as you have, support her in her decisions, but not financially. If she really wants your help, or anyone's help for that matter, she will ask for it. As long as she doesn't ask for it, don't be a hero and do it for her. What many guys don't realize is, women are more than capable of figuring out themselves what they want and how they want to solve problems. If anything, she might just need your support emotionally and that is it, until she has her career and finances sorted out. Trust me, it will mean A LOT more, than you solving her problems for her, and she ending up never learning how to do it herself. That will make it better for you too, if she ends up the one with you for the rest of your life.
