I fell in love with my best friend, and she ended up cheating on me with the man she broke up with because he cheated on her. She told me how he hurt her, she became emotionally unstable and suicidal because of him cheating on her. I helped her get back up on her feet and helped her stay positive, possibly even ALIVE in the most extreme cases. The relationship was fantastic while it lasted, there was no doubt what we had was love. At least thats what I though. Turns out I was just her tool. Dont fall in love with your best friend, or theyll become a sour taste in your mouth afterwards.
