Request for further evidence - Decided to divorce but have not proceeded

[jaekh 0]

Hello everyone,

I'm in somewhat of a unique situation here and I'm looking for some guidance on the best way to proceed.

I married my wife in July of 2015, filed for adjustment of status in July of 2015, was approved for conditional permanent residency in December of 2015, and filed for removal of conditions in December of 2017.
Due to delays in processing, I have received an 18-month extension (expired June 2019) and attained an I-551 stamp (expiring July 2020).

In early September I finally received correspondence about my case, requesting further evidence to remove my conditions.
Many of the things that they are requesting from us, I cannot provide.
We've always kept our finances separate, we are renting part of a house from one of my wife's family members and have no lease that has both of our names on it, we don't have any children, we typically don't take pictures of ourselves together.
What we can provide are copies of our IDs/licences showing the same address, tax documents, receipts for plane tickets for us to visit my family, and multiple affidavits from friends and family stating that we entered into our marriage in good faith.

Where this gets a bit tricky is that we want to divorce.
We got married very young and didn't know enough about ourselves and each other, and we've come to the conclusion that spending the rest of our lives with each other is not something that will make either of us happy.
I don't wish to leave the country as I have started a career and made many friends here.  I also know that there will be times where my wife and I will require emotional support from each other.
We're still very much on good terms with each other,  still (currently) living together, and I've been told that I can still count on her full support through this whole process.

We aren't looking to wait much longer on filing for divorce, so is it in my best interests to submit the minimal evidence I have and continue with the original I-751 filing, and THEN divorce? 
Or should we proceed with a divorce and file for the I-751 divorce waiver?
Should I try to schedule an interview with a USCIS agent for the both of us so we can explain our situation?

This is an unbelievably stressful situation for me, to the point where I'm almost considering moving back home and starting from scratch.
I apologise if there has already been a thread covering this kind of situation

Thanks

Submit what you have. Write an explanation that you keep the financial separate and get the family members to write a letter that you guys live with together with them. 
submit what else you have from December 2017 til now. And then I would also switch to a divorce waiver as you are starting that process up.
