I'm sorry, but this situation you posted about the N400 denial is completely irrelevant. 
 
OP, I'm glad you found the birth certificate of your spouse. Bring it just in case. Good luck 

Thank you! I found a copy of his birth certificate. I have evidence to prove we are no longer together and why. I hope this will be suffice. 
Thank you

OP may be asked about the marriage based on which the GC was obtained. However there is no way an IO would ask for the original Birth Certificate of the USC spouse who is no longer in OP's life. Handy to bring copies of such though that too only if available.

You are welcome Alison. I am quite sure the resources available to you are plenty. The questions will be the same no matter what the format. We happen to live very close to the local field office, so it was easy to get the booklet. The Hawaii field office is relatively small, so Joan's oath taking ceremony was small--I think 30 or fewer people. There were several ceremonies scheduled for that day. You said that you lived far from your field office. Ask if they offer oath ceremonies the same day as the interview. Some do, some don't. The Hawaii office offered same day ceremonies for people who lived on "the Outer Islands," or islands other than O'ahu. We live on O'ahu so we went back for the ceremony a few weeks later.
 
Back to the test: relax and just study a little at a time. It was already mentioned, but I will say it again: pay attention to the question. If it asks for ONE answer (when there are several acceptable answers) then focus on ONE answer. Don't make it harder on yourself. I highly recommend this "classic" VJ thread by @TBoneTX to ease the stress of the exam. It is hysterical (spoiler: Mrs. TBoneTX passed the test).
 
You will be fine!

I actually disagree about answers applying to “every democracy” or names/events  being pretty known. Not one of the government questions could could have been answered correctly if I had used the Australian system as the basis. It is appropriately US centric and US specific and in some places highlights differences with other countries rather than similarities. 
 
That said , it is not a difficult test for most people .. but there are some who will struggle for many reasons outside their control. Sounds like OP has a plan that will bring success. 

I wrote out all the questions using the USCIS pdf .. and one answer .. sometimes  there are several .. and every day for 3 weeks I would read the question and answer  out loud as one sentence The more senses involved in the learning process the better it sticks. So i was reading speaking and hearing it all at once. That way , when the IO asked” There are 13 original states of the union, name 3” I was already finishing the “sentence” in my head and automatically said “New Hampshire, New Jersey, New York”. Plus, if there was more than 1 correct answer, I only learned the easiest !! Didnt need to prove myself more than that ! 

It's a total pool of 100 questions and the list is available online.  The examiner will pick 10 from the pool, and you have to get six of them right.
 
My wife had a CD that had the questions and answers, one after another.  She listened to it (over and over again...smile) when she had spare time.  You don't need a CD...you can sit there and read the questions and answers into an audio file (.wav, .mp3, etc.) and play it back on whatever you use to listen to music.  There may even be online files that have someone already reading it all out and you just have to download one.  "Over and over again" was the key for her.
 
I also got her the flash cards.  But she didn't use them that much, and she tells me the CD audio is what got her to pass.
 
If you're someone who learns better by reading, print out the questions and answers and carry them with you.  Take them out and read them when you have time.  (You can also store the website or a document on your smartphone.)
 
Do not spend a lot of money on "aids" to learn with.  It's not needed.
 
Regards,
Vicky's Mom
 

You don't need him to file for divorce, file yourself. Either way you are eligible to file under the five year rule and divorce won't effect a thing.

It's fine just be open & honest with USCIS about your marital situation. These things happen & USCIS employees realize that.

@Alision_J36 Just jumping on here to back up Rocio and Carmel's advice. Even if your spouse doesn't want to cooperate, you can obtain a divorce. It may be relatively easy now that your husband has come back on the radar, because you could probably find out information to get him served this time (his place of work or home address, for example). If he doesn't respond to the Complaint for Divorce, you can request a Default Judgment. Laws vary by state so look it up for where you live to get more info. If you can afford a divorce attorney, that will help you navigate the process. Divorce attorneys also usually have contacts that can be useful in getting someone served (private investigators, process servers, etc).

So sorry you’re in this predicament. I’m not very knowledgeable on the topic, but I don’t think the other person needs to agree to divorce (I can’t remember the word in English). I’m pretty sure you can do the divorce yourself, but I’ll let others chime in. 
Also, just in case… do you have any paper trail of the divorce you filed? Even though it wasn’t “successful”, it might still be worth getting evidence that you filed just in case and for your peace of mind. But you should be fine since you’re filing under the 5 year rule!

Married in this case.
Separated requires a legal separation order.

Yes.  You have been a legal resident since the day your Adjustment of Status was approved (normally the residence since date on your GC).

Wow. I could've filed since 2020 if thats the case. It's never too late though

In 2018, did you get a 2 years or 10 years GC?

5 years from receiving your first Green Card.  I assume you filed to remove conditions  We filed my wife's removal of conditions back in March of 2019......still waiting for the interview.  My wife received her conditional GC in June of 2017.

We submitted my wife's N-400 based on the 5 year rule this morning.  Although she had to list my address, we didn't have to provide any bona fide marriage evidence.  In fact, it was an easy & simple process.  The hardest part was compiling our address history and finding the dates of her travel outside the US. 

You will need to file under the 5 year rule.
