My girlfriend cheated on me with my only real friend and left me for him. We were very happy but then I questioned my love for her and became distant. I didn't think she loved me as much as me. Then I realised how much I loved her. but at this point it was too late. She was already retaliating by being distant with me. So she started upping the game with my best friend behind my back on snapchat. All I can think of is how much I lost. Now I am alone.
