Power of Attorney Fraud for Loan?

When my husband was deployed , I ended up running out of cash and took out a credit line of $ 2,000 with his power . It was a special power that had military representation . I did not ask permission to my husband first , really. He communicated with a married woman and sending pictures back and forth with her and I got angry. MedlinePlus Long story short , he's crazy , he met someone else , wants a divorce , and says he can get me for fraud because it applied online as if I were him ( in his name ) , not to mention power. Basically I went online , put your information , and took out the loan because it was the only one with a bank account because it does not have one , and paid all the bills and gave me an "allowance " each week before deployment . Is this true ? Can it really fraud ? I have fear.
