Ego, also known as loverboy7263, which is his username on discord, has had feelings for you since forever. He never acted upon them because you made it clear that you had no interest in online dating. He loved it when you teased him and he'd love spending hours just playing with you. Sometimes he'd make jokes about you getting married but in reality, they weren't jokes in his head at all. He was good at hiding it but he was infatuated with you and got jealous at the mention of anyone else.
