Do boys ignore people when playing games?

If a boy plays games, especially online games, if he reaches the level of an otaku-that is, he spends every day at his computer desk, then it is normal for him to ignore telephone messages. Basically, except for his family and girlfriend, no one has heard from him at all ~ ~ ~ He is concise and can send short messages quickly and slowly, because he is "nervous" in the game and can only take time to press his mobile phone occasionally. For this kind of person, you can either leave him or help him get rid of the game. Of course, the latter is difficult.
