Question Author
He was honest about his marriage but he was new to the company and so was I so he barely spoke to anyone as he is shy and a private guy but once you got chatting to him he'd mention 'my wife' now and then.
I know him quite well.. Me and him chat A LOT.. we email during the day, go on lunch together and he will always come to my desk for a chat.
For him, I probably am just a young girl who flirts with him, who he wouldn't mind a bit of! Nothing to ever leave a marriage for. But men are different... no man has ever walked away from a marriage because 'he was bored'. Men don't leave unless they have someone to leave for. If a man is getting sex, food and sleep without being nagged 24/7 then even if he is bored of the relationship, he will stay. Men don't need the emotional stimulation like women do. That's why they don't leave until they have met someone else. They don't realise they are unhappy.
I don't think he'd leave her anyway.. child or no child! He is with her through habit if nothing else and that's the hardest thing to break... especially when she probably thinks they are blissfully happy so she will never end things. He will spend the rest of his life being with her, wondering what life would have been like if he'd had the guts to leave, but never really doing it because he is scared of what he would be giving up!
