Hi thanks for your approach to us..
I understand concerns towards certain issues with your son, and certain commitments with your personal life.
But try to think of your priority, if it is son, fix yourself to give him time to build a rapport, affection and bond age, he could be observing how other children get the presence of parents and would expect the same from your end, which might be result of his behaviour.
Because of his emotional distress he lacks in concentration, confidence and interest.
