It’s a very difficult situation and it sounds like your son needs you and moving to a different country although it could be a fresh start might be tough on him if he is really close to you. Does your wife have family in SA.
Maybe talk to your wife about staying in the country you are in and explain your thoughts on wanting to be there and guide your son.
Its hard to say what you should do with regards to custody but you sound like a great dad and I’m sure you will make the right decision
