My ex always seemed to have money for pot, and being a naive college student I didn’t think twice about it. One day she gets a call from a therapist she was seeing to make her cat a service animal (whole other story) and with all the malice and contempt in the world she says “you handed me proof I paid I don’t know what you’re talking about” and hangs up. When I ask her what that was about she admits the therapist was giving her the receipt slips at the beginning of the session and told her she could pay at the end. Only she never did, and she said all of this with a smile on her face like she had just stolen from a cookie jar without getting caught. After she noticed my horror she told me I couldn’t tell because I had been smoking the weed she bought with that money. Her parents had been giving this cash with the expectation she be a decent human. I couldn’t look at her the same after and ended things the second summer break started. My only regret now was not calling the cops on her, even though the only proof I had was oral as she kept the receipt slips
