She wasn't with you shooting in the gym, but for whatever reason, your girlfriend has access to your funds. After the dissolution of the relationship, she may feel like she has nothing to show for all of the time she put in. Because she can't get her hands on what she really wants (your throat), she'll opt to treat herself to a subsitute—with your money. For the sake of your credit score, make sure that you have all of your cash and plastic currency on you before breaking the news. Also, change the passwords to your online accounts. She could buy herself new shoes right in front of you as you're dumping her (and we wouldn't blame her).
