(This has been bugging me all night and day so I feel like ranting)
You think you know people but eventually the truth comes out. You think you can trust people but eventually you learn you shouldn’t have. Like of all the people you could have had sex with, you, my best friend for whom I’ve known since I was 11 years old, decided to have sex with the love of my life, the one who means the world to me, and the one I couldn’t stop loving even if I tried? I would understand it if you had sex with him before he came into my life, or at least before we were together. I would understand it if you didn’t know we were together, or at least that I loved him. But no. You had sex with him after our brief breakup. You had sex with him knowing of our relationship. You had sex with him knowing I loved him. I can’t forgive you, especially now, since his health is on the line because of you.
