Amen brother! I have spent so much time wrapped up in my W over the past 13 years that it is like I don't know how to do things on my own. I have been reading "No More Mr. Nice Guy" which is geared towards guys like me who need to figure out how to be OK with themselves. The premise is that until you can be happy with yourself, there is not much you have to offer to another person.
My W also seems to enjoy my company, it is just that she seems to be completely checked out emotionally. I know first hand that this is extraordinarily confusing and frustrating (the famous limboland). After 4 months, I am finally starting to see that being available is not the answer to this problem. It is very hard to move towards being unavailable but I think it is the only way to go in cases like these
