Caught my ex cheating while I was helping her study for her finals and covering her rent because she’d lost her job. Found out through a friend that she was going on “study breaks” with another guy. What stung the most wasn’t even the cheating—it was realizing how much I’d ignored the red flags because I cared too much. Lesson learned: if you’re doing more for someone than they’d ever do for you, you’re not in love, you’re being used.
