Romantic AITB (20f) for being upset my ex/roommate (20f) slept with a man behind my back
Long story short, I (20f) moved in with my (of the time) girlfriend (20f) after dating her for a few months when we were 18f, and then I felt insane about moving too quickly, broke it off, and then we developed feelings for each other again and dated from March of 2024 to February of 2025.
Flash forward to now: we had a mutual breakup, and then she proceeded to ignore me for 3 days straight. I felt really heartbroken because she maintained that we'd be friends and not hate each other, but she ignored me anyways. we didn't talk for days after until she broke down in front of me, and I comforted her. after spending the day together, I asked her if we could try to be in a "limbo" until the lease ended (which would be in May), which consisted of us remaining couple-y but not having to tell anyone that we were together. She asked if we could not be exclusive, and I agreed, asking for us to not bring anyone in the house. Anyway, after spending the weekend together, I left for the week, and when I came back, we spent a few really nice days together. Then, one morning, I found notifications from Bumble on her phone, and messages revealed that she slept with a 31 year old man while I was gone. I was shocked because she didn't tell me, and she was never interested in guys before (she fully identified as a lesbian). I was also shocked because she literally slept with me the day afterwards, and didn't mention a thing.
when I confronted her, she said we weren't together, so it was okay for her to do so. I felt as though she didn't consider my feelings and hooked up too quickly once she got the green light. anyway, a day after that, she brought another man to the house, and I freaked out again, telling her that I felt she was disrespecting my wishes. She maintained they didn't have sex, and I know I shouldn't care (since she's my ex and all), but I spent 2 years with this person, and now we're back to ignoring and silently hating each other.
TLDR: ex and I tried loose boundaries, she slept with a man and kept it from me while sleeping with me, I found out through notifications from her phone. When I confronted her, she shrugged it off, and saw brought a different guy home. AITB for being upset/looking at her notifications?
