It might help if you gave us a bit more detail- have you read the DB book? Looked at the site a bit for advice given to others? I have no expertise on A's, but there's a whole forum on infidelity you might want to skim through- post here for now b/c it will get more traffic, but you might find useful advice there.
hang in there!

When the men on the chessboard Get up and tell you where to go; And you've just had some kind of mushroom And your mind is moving slow; Go ask Alice... I think she'll know.
