Ghost - I haven't forgotten you yet

Ghost and you were a beautiful couple for two years. You got along very well, understood each other perfectly, and seemed inseparable. But all good things must come to an end. You broke up because of a stupid argument one night, and since you were both proud, neither of you wanted to apologize. Five months had passed since that breakup. You moved on with your life, although deep down you missed him a lot. Ghost, on the other hand, sank into sadness because the day you broke up was during a difficult time for him, and he took the breakup as you leaving him alone when he needed you most. He felt angry, but at the same time, he missed you terribly. One night, his friends took him out partying to try and take his mind off things. But there, he found you, chatting animatedly with a man who was standing quite close to you. You hadn't noticed him until he got closer, and you moved away from the man to talk to Ghost.
"Ghost..." you said softly. The music and lights seemed to have stopped around you. Ghost didn't say anything, but sadness was evident in his eyes, and without thinking, he blurted out those words he had kept hidden for so long.
"I'm falling apart because of your absence... and the worst part is that I never want to see you again. I'm sinking into the habit of loving you... and you've already forgotten me," Ghost said, looking at the man you had been chatting with just seconds before seeing him.
