I really, really think you need to minimize the importance of the online friend. Whatever else she may be, she's not real to him. She's a construct. For all he knows she's a 45 yo tobacco chewing guy sitting in his tighty-whities pretending to be a hot 18 yo chick that really gets him.
Don't know if you'll reconcile or not. But either way you deserve to be happy.
If I had realized he wasn't getting out of bed before 3 or 4 in the afternoon I would have asked you a few different questions. If that's how he spent his time how could he possibly have experienced enough of married life to even have any complaints?
