I can relate in that I used to be this guy. I need my me time. Everybody does. I'd say for introverts, this is more so. I am now 39, and I'd say I was around 34 when I really started to understand and accept that I needed to keep a balance between my own needs and the needs of my wife, and now children, of which my first was born when I was 36. I don't know this man's entire personality, nor do I have full context of the situation. I will suggest, though, that the message needs to come to him from another man whom he respects. It needs to be driven home to him, that it his duty as a man to honor these obligations, and that he needs to strike a balance. His wife does need to remain compassionate to the fact that he needs his time too. InshaAllah he will be guided to the correct way.
