Oh, you sound like an adventurous, thrilling person. Have you ever been into drugs/psychedelics or even recreational marijuana?
This sometimes stays within our body if the THC level dosage is unregulated or if we blindly administer it. You do sound intelligent.
Have mysticism intrigued you by chance?
Do you plan a family? Perhaps it will change life perspective for you?
You sure are lucky to have a wife like her, and please prize her. But do you model the emotion and not feel inside?
Perhaps just detachment in your personality as you have been successful and independent and do not much attention to feelings because you think it does not simply work?
Just humble advice: do not let go for such a wife. Also, do try spiritual meditation and reconnect.
I am sure you will find something exciting if you believe in spirituality.
