My question involves criminal law for the state of: California
My Ex-GF and I were a live-in couple for several years, we were like financially "unified", and I was the person who pays for everything (groceries, electronics, travel, etc). Most of these charges went to my Credit card (credit card has only my name), so, when it comes to payments, we pay a part out of her Bank account (she acknowledges this) and the other part out of my bank account. Few times, she transfers money from her bank account to mine, and the credit card balance is fully paid by my account. Fast forward to present, the last credit card statement was about 18K dollars, and I paid about 12K from my bank account, and about 6k from hers. She and I broke up just a few days later because of relationship problems.
Now, after a month, she is accusing me of stealing money from her account

. Could this be a something bad against me? I have all the statements of my credit card and my bank account. We verbally agreed to pay the credit card together, so she never have to carry money with her. Any advise, help will be greatly appreciated!!!
BTW, Excellent Forum

, I've learnt a lot from it.
