She had been cheating on me for a while with a couple of guys and she hid it from me. So when she confessed, I mentioned that I needed a cigarette. And so she berated me for smoking and broke up with me because I “breached her trust” by smoking cigarettes when I had told her previously that I didn’t smoke. It caught me so off guard that I actually started to feel bad. Until I hung up the phone and realized what had just happened.
That excuse still makes me think, “wut?”, to this day.
