I made a new friend recently, a really sweet girl that I think deserves the world. I just learned yesterday that she has a crush on my ex boyfriend, who's also my bestfriend. I had hooked up with my ex the night before, and I'm really struggling with my feelings for him. Recently another guy has been on my mind, and I really like him, but I can't stop thinking about my ex. I've never felt so guilty in my life, and I have no idea what to do
