Have to see the validity of Jeremy'M's points. It makes sense Chime/Bancorp would not go after her, in their eyes the missing monies could have been taken out to support your life while you were gone. You set yourself up. If you decide to pursue her in small claims court, you will need more than a camera shot of someone withdrawing monies, remember it is your word against the other person's who was "trying" to do you a favor. You are the one who is going to have to have evidence, direct evidence, that the transactions were not for your benefit. It was you being gracious that she took care of business while your life was on hold. You will need actual transactions of her activity while on your dime, retracing her footsteps.
How does the bank know you may not be trying to double dip? In their eyes you 2 may have been working together and trying to commit a fraud on the bank.
Best to you.
