in my opinion, no news is good news so far. USCIS is notoriously slow, no matter what center is handling your case. I believe the current processing time is up to 14 months. I would contact them to inquire about your case when the 14 months is up.
How did you file your petition? Did you do it yourself or did you retain the services of an attorney?
The fact that you had previously petitioned for your ex-husband will more than likely be a red flag. I am sorry that he was a cheating dirt bag by the way.
And depending on the age gap, that might also be considered a red flag as well. I have a large age gap with my husband as well so I went above and beyond to submit as much evidence of our bona-fide marriage as possible to over shadow that red flag.
The best advice I can give is to remain calm, don't stress out and follow up with USCIS. This whole process is stressful enough without us adding to it. Whenever you start to stress just remember that you aren't alone in the process and that us here on this form are going through it with you.
Best Wishes
