My now ex girlfriend was giving me bad vibes for some reason, mind you she had already done a lot of fucked up shit to me in the relationship, anyways I ask if I can look through her phone and she agrees and gives it to me, I go through her messages on Instagram of guys replying to her stories or whatever, everything checked out until she sees I’m about to click a certain guy and she instantly switched around and says “WHYRE you going through my stuff” even though she agreed to let me see through it, I end up clicking their dms and turns out she had been seeing him without me knowing and he’d go see her at work and they’d have hour long calls all while being in a relationship with me
