Your girlfriend has no impulse control - it's a sign of immaturity - and unless she learns it, she won't survive in the world. You have to make her be responsible by not loaning her money just so she throws it away. She must be confronted by her problem or it will be much worse for her. You have to get serious with her and tell her that you are not propping her up anymore. She has to learn to stand on her own two feet. If she won't try to curb her spending, then you will have to leave her or else she will drag you down eventually too. This reckless spending behaviour should be treated like any addiction. It must be controlled. Help her draw up a budget and stick to it - after all the bills etc are paid and some money is banked, she can then spend what she wants.

tell her your over her spending and you are no longer sharing your money and if she does not want to save hers she cannot expect to have yours, I can see this ending badly, I would let her go, not worth it, she will send you broke then find someone else, good luck
