I had the chance to date a beautiful girl. We worked together so I decided to not do it although I was starting to like her. Instead, I went back to an ex. The new relation with her was brutal and she treated me awfully. It was just the worst. It ended. Now it has been half a year and the girl I said know is dating a friend of mine. I don´t think he deserves it because they have a lot of issues. They fight a lot. And she shows signs of having not forgot me. I envy my friend because she´s awesome. I can´t take her out of my head. I´m starting to think how little I can respect my friendship with my friend, just to have her. And I know it´s just wrong and I have no idea what to do.
