Please stop. You cannot force a relationship between other people, just like you cannot end one. Do not continue to go down to Durban, heap up expenses, all to no avail. Rather explain to your son, that his daddy loves him very much, but have some things he needs to sort out in his head. And that you need to give him time. Going to the dad and the dad refusing the child, results in rejection - over and over and over again. It's worse than staying away. Please stop. Decide what you want. If you still want a relationship with the dad, or not. Take it from there. But don't force either of them into a path. Children are very resilient - and very smart. Your son understands more than you know. Leave it be, it will work itself out. Just never bad mouth the dad, put your son first (which sometimes call for drastic action that may hurt now, but save in the long run) and ensure your own happiness as well. In that order. And it will work out.
