I experienced this kind of situation where my gamer friend suddenly ghosted me for over one year and a half. I messaged him everytime because i worried for him, if his okay but, he didn't message me. Day by day i messaging him that i hope his okay and I'll still be here waiting for his message. However, until i overthink if i did something wrong, if its my fault that he didn't online anymore, my feelings and emotion are hard to control that day, a mixed of sadness, anger, confusion, doubt until my mental and physical health getting worsen and didn't take care of myself for over a year. But thankfully my other friends comforting me for almost a year, and thinking of him, my gamer friend, didn't feel hurt anymore but i still think of him. I realized that i need to accept because it's not permanent to stay forever with him and keep playing. Hahaha just sharing
P.s. We reconcile again but it's not the same anymore. But that's okay because i know now why he didn't online 💓
