I have to say good for you on being honest, I have done the same things and ended up with the same results. If he is a good man, it won't come back to bite you in the ass because honestly, it was him that started the mess to begin with so really he should feel squared out with you. I mean maybe I shouldn't say that as it is, but it is still the truth. If he ever brings it up again just explain it once more, remind him that you love him and that you are happy where you both are at, at this point in time and that you wanted to make sure your marriage was on a clean slate. If things had been worse, I could see it ending badly but the point is, it was more or less nothing on your part and you should have never felt guilty to begin with. Hell, I wouldn't have even said I felt guilty, I would have told him he needed to know and why I did it. Irrelevant now though, just wish you the best of luck in your life! Stay good!

Wish for a pile of shit to turn into gold hard enough and guess what? It's still a heaping pile of shit.
