With a little bit of space between starting this thread, confessing to my wife, and now, I just want to say that God has been at work in our lives. Things have been great between my wife and I - even better than before my mistake.
God is drawing us closer every day and it's having a profound impact on our personal lives, relationship with each other, and relationship with Him.
I ended up sick, likely as a result the poor diet, lack of sleep, and stress (per the doctor) I experienced leading up to my confession and I'm still dealing with that, but otherwise things are going well.
Not much more to report at this point, though I may not be back for a while. I need to continue to working to improve my relationship with God, and my wife, and right now that means leaving this thread for a while so as not to dwell on things.
Thank you everyone who commented, prayed, messaged me, etc. It means a lot, and continues to have a positive impact.
