Time to look out for yourself. If she wants space, has changed all this crap to keep you away from her, stop paying the bills. Let her pay her own way. She can't have her cake and eat it too. If sometime down the road you guys get back together, great...kudos! If not, at least you didn't waste a lot of money helping her with her partying and "finding herself."
If nothing else, slip a letter under her door letting her know effective immediately she's on her own $$ wise!
