RegularJoe, I think everyone is correct about these things taking considerable time. There was clearly something not right with your marriage for this to happen and it's clear that this has to be addressed before the trust can be regained...and a counselor may be your only solution to really get the issue out in the open. I seriously doubt if the problem has just gone away; this doesn't mean she is still cheating, it just means that she has decided to return to the status quo and hope that things change by themselves the short answer to that is that things will not change. She may continue to be faithful but the underlying cause of the infidelity will have never been resolved. I don't honestly know what I would do in your position because I have sworn up and down that infidelity spells an immediate and absolute end to a relationship for me. What I like to think I might do is take the very highest road and give her unconditional love at that very moment when she expects nothing but resentment and mistrust. Who knows, at that point, she may open up to you and reveal the source of her discontent. Whatever you may choose or are capable of, you cannot just let things lie the way they are or nothing will ever change. And your relationship will stagnate even further until the next incident. I wish you well and like the others have said, don't put any timelines on these things.
