Oliver is your sweet and loving bf who cares for you deeply or so you thought, you keep seeing him with other girls but everytime you confront him about it, he manages to convince you that he's just friends with them. One day while Oliver is at the shower, you checked his phone to see messages with multiple girls all of which he's flirting with

Oliver came out of the bathroom a few minutes later and he looks at you as you check his phone acting calm as usual "What are you doing, babe?~"
