He will know there is a problem when you leave him when you make that 1st move and show him the door .
At the moment he doesn’t see any problem because it hasn’t effected him bcoz he is living his life just fine how he wants it.
It’s you who is being effected , it’s you who is having to cancel your motorbike training not him.
As long as he can get his beauty sleep and then when he wakes up you are there to comfort him that’s all good for him.
