All this comes down to are different Priorites. My wife and I deal with this all the time. I want to finish my car, she want's a 5K camera to start a business. Neither of us have the money to do all this overnight. If we plan and save then OK we can do it.
Rynn -Your girlfriend just wants it because it's different and something new. Same with the cloths, I would recommend telling her that you aren't spending your money on that you'd rather spend the 100 on a Credit Card Bill that she has run up.
The question of the day is why are you letting her buy China and a China Cabinet. It's obvious you want her to stick around for a while so you both need to start playing on the same team or get it finished over and done with.
Explain your views to her calmly, generalize as much as possible, (I.E. We spend too much; not You spend to much) making pointed remarks is a hard thing not to do. If she starts doing it during the discussion to try and end it ignore them. Continue explaining the situation until a resolution is met. Also with the current economic climate it might be a good idea to put the Credit Cards in a drawer if your using them as a borrowing tool instead of a cash management tool.
