I could not resist the temptation to be the 3rd Pam to respond to your question.
I would say that your timeline has things moving along pretty quickly. There are more than a few of us here on the bb that have H's who have been involved in R's with OW's for longer than your H's seemingly lasted.
Are you positive that he is no longer having an A?
Just keep reading the board, looking for those who have similiar sitch's, who can impart wisdom and encouragement.
This takes time, lots of it, more than you could want or anticipate.
What is your H's spiritual status? That could be a major contributing factor to your dis-connected feeling.
