Don't cry over it! I believe you. Only someone who really had good intentions would do something that naive ! And I mean that in a good way. I did the same damn thing coming into Canada. I can share my story to make you feel better if you like !
I think it's hilarious some people want to give you such a hard time. Legality is just legality. It's legal to do some things you shouldn't be able to, and illegal to do some things you should be able to. At least you and your husband are in a genuine relationship and wanting to immigrate for genuine reasons. That's more than I can say for some people. Marriages of convenience and such (my foolish father-in-law is in a horrid situation such as that).
I do agree it would be best not to risk AOS. You'd be putting more on the line than is worth, considering the consequences of it being denied, and that you don't have enough proof that immigration would listen to for your case. I can only imagine the despair you must feel at having to be separated by up to a year. But with immigration, it's important to try to keep your chin up and keep positive! Who knows, maybe you go back and you are approved in less than 6 months .
