I still use my ex-FWB’s private parking garage code

Last year I was in a great FWBs arrangement with a lovely woman I met off Tinder. One of the many of the many perks of this arrangement is fairly obvious, but the other two perks were having a new friend to send insta reels too, and being able to use her private car park. She lives in a busy city neighbourhood that is bustling with culture, cafes, people and sadly...expensive car parking. So as you can imagine this was a god-send when I stayed over, as I could stay without having to pay for parking without worry of getting a parking ticket. Sadly we ended our arrangement - it was slightly confusing at the end, but this doesn't matter too much. I haven't talked to her since. My confession: even though we haven't spoken in 9 months, I still use the PIN code whenever I'm in the area and need a spot. Although I have the same car, I changed my registration plate, (making some dosh of my old personalised plate). I'm hoping this might help me go under the radar. I have no idea if she’s noticed, and if the passcode will work, but every time that gate moves, it's a mix of pure relief and slight adrenaline.
