If A says," I don't want him to fix my computer this time because he always leaves me a limbo."
what does "limbo" mean here?
I just know "limbo" is a game.
A probably said..."leaves me in a limbo".
Limbo technically means a place between hell and heaven where the souls stuck for a long time before they are ready to go to heaven. Souls that remain in limbo are usually said to be sad, lost, forgotten and deserted.
Keeping that in mind, you don't want him to fix your computer because it will create a limbo for you (figuratively speaking)...you will be lost and confused after his help instead of being able to use your machine.
The phrase is 'in limbo' ('he leaves me in limbo')-- in that region between heaven and hell where some souls must wait eternally for want of a proper baptism. The key phrase is 'wait eternally', usually with the added irritation of uncertainty about what's happening with the computer repair.
