I've screwed up plenty of times. What I I remind myself is this: if my spouse wasn't screwing things up so bad and trying to destroy our family, I wouldn't even be able to make a mistake while I'm trying to make things better. So the fact that you took a step back is still, at its root, due to the spouse.
When coaching sports, I always tell my teams that I can live with mistakes while giving effort and acting with good intentions. I know everyone on this board is doing that, including you. Dust yourself off and get ready for the next play. The other team (our spouses) won't stop playing while we're focusing on the last one.
