single mother is the best... Yonario

It is two years since I married my wife. it's a mediocre, but i was happy... until i met him. "Momoko and her husband love each other, don't they?" "Of course ..." "But ... Isn't your body a different thing? You can't have an affair unless you get caught up." But ..." "Can you put up with only Momoko for years to come?" Is there a man who can put up with this invitation? what should i do?
