The Uncle aka Mum's long-term BF loved her so much that he couldnt let the son go after she dies and got all wierdly obsessive and creepy. But somehow there was an iota of rationality left in the Uncle where he realized he needed to let him go and live his own life, hence sending him on that outstation errand. And MC sounded like he forgave him somewhat in the end, as he seemed to understand what drove Uncle to do what he did. So first, he obsessively loved the Mum, then he obsessively loved the son. Creepy AF yes, but pretty sad too.
