as long as the non-o is based on marriage. If someone got one based on retirement but is married they need to match what you originally sai 800k etc. Just being married doesn't change anything, you have to meet and maintain validity for the visa you have.
if they didn't respond after you uploaded the requested documents they m8ght have missed them. From their standpoint they might have assumed you never responded and so were no longer interested. But just a guess. You could always try re-applying.
You can leave. But you are taking a chance. They can ask you to come in any time up until a final decision is made. And if you are gone you will lose your fee and have to start over. Most places it is less than 2 weeks to get a decision.
so your YEAR extension ends after 89 days? And you have done the initial extension 8 times? Maybe you should read your comment to see if it makes sense before posting.
