Debts incurred by ex-girlfriend

I live in Indiana. I lived with my girlfriend in my home for 1 year. We recently broke up and she left me with credit card debt. It was my account and she requested a card for herself. Can I recoup half of this debt since she lived with me and had access to this account? Also, we had a joint checking account and she made a withdrawal of all the money in the account after we were broke up. Can I get half of this money back as well? Lastly, she may file a countersuit on me about items she gave me as gifts, that I have solid proof of proving they were gifts. Does she have a case with no proof of purchases? Thanks.

Q1) "Can I recoup half of this debt since she lived with me and had access to this account?"
A1) No. Unless you had an agreement that charges made by her were loans and to be repaid, her charges would be considered gifts.

Q2) "Also, we had a joint checking account and she made a
withdrawal of all the money in the account after we were broke up. Can I get half of this money back as well?"
A2) You can very probably get a judgment for ALL money that she took that YOU placed in the account. If 75% of the deposited funds were yours, you would get that 75% back.

Q3) "Lastly, she may file a countersuit on me about items she gave me as gifts, that I have solid proof of proving they were gifts. Does she have a case with no proof of purchases?"
A3) Same 'rule' applies to her as in A1 above. Unless she can prove to the court that money was an agreed loan, she has little or no chance of recovery. Even less if she gave you 'gifts' which obviously can't be subject to a loan agreement.

"Thanks."
Your Welcome.
