Mate - you may not be broken - but your marriage is.
I get that you're into Tolle and I get that you perceive yourself as very self aware and I respect that you've told the board you are interested in concrete examples of things that worked, rather than advice on liturature etc - but if that's the case, what do you want?
Do you love your wife? (whatever love is?) Are you prepared to have an affair - and if you do will you tell your wife - or deceive her? If you are in life transition and you plan to leave your wife, on the basis of a conversation about sex you had several years ago is that really fair to her in the here and now? (acknowledging it wasn't really fair for her to ask you for the no sex rule to start with)
There are very few people who will be able to give you their personal experience based on that set of circumstances.
I can give you my experience, based on not nearly as extreme, but some similar circumstances ...
When I was 33, I was married to a devoted, loving, 50 year old man. We'd been married for 10 years. I loved him with all my heart, but the sex wasn't as hot as it had been, he prefered to play golf or lawn bowls to tennis or bush walking. He liked to take our holiday's in New Zeland where we could fish and golf and I wanted to vacation in South East Asia and Africa where we could adventure and explore. My career was just taking off and I was ambitious as all get out. He was winding down from a very very successful career. I think we were both in life transition - but probably mostly because of the age gap our transitions were taking us in different places.
I left him.
It was the most stupid thing I've ever done.
4 years later, I'm still really sad about it.
I have great adventures now, my whole life is an adventure and I have a great sex life whenever I want it, my career has just gone from strength to strength ... but it's lonely being free my friend.
I miss my husband, my friend, my mentor, my (at times infrequent) lover.
If you love your wife - don't just leave her because you feel as though you get NO...thing from the relationship. Talk to her about where you are at. This is a different place than you were when you made the no sex agreement and she can't read your mind - she doesn't know you've changed, or are considering changing, it.
If you love your wife you should think very seriously about the implications of leaving the marriage. You'll be free - but it's not all it's cracked up to be.
