God I Quit

Being the best example of a Father I can be, and even tithed my 10% as often as I could. I thought I was a decent person, saved by the cross of Jesus Christ. I mean I'm only human, I'm going to make a mistake once in a while. Until one night...everything changed.
I'm driving on the freeway, westbound towards LA. It was 10 o' clock at night. My eyes filled with tears, barely able to see the road in front of me. I'm taking deep breaths as I cry out to my Father in heaven, "God, what have I done!?"
Hours earlier...my wife and I were having a deep discussion about the past and she tells me she believes God is telling her there's something to be said. I finally confess that 4 years ago, I kissed another woman. Of course she's very upset and hurt, and asks if there's anything else, and I of course, say no.
Then God tells her, "There's more he needs to tell you." She continues to press on asking, "So you haven't done anything else with any other woman?" As always, I told her, "No, I haven't done anything else. You're crazy to think that." But her discernment is strong and God isn't going to let it go this time. I feel this tightness around my throat, I can barely breathe.
