Citizenship

I came to the USA with my family and our kids with 10 years green to all of us. However, after 3 years, I caught my partner cheating with someone, and we separated to live different state. He impregnated another partner after 3 years. I filed a divorce and the lawyer advised me to file the divorce based on separation because cheating will take forever. The divorce was signed by both of us as uncontested and the court granted it. But I get the green card through from him. Although, we get the green cards the same time for all of us, wife, husband and kids. None of us are citizens currently. The kids stay with my partner, but I agreed to give some support for the kids which I fully paid throughout the period. They didn't ask me any question about my family and the kids during my N-400 interview. The interview was June 2019. I have taken 6 years with permanent residence status and I decided to file for my N400. I have attended the N400 interview over 6 months ago, but no decision was made. I have called the 800 number times without number and used congressman, Senator from my area and the response was always generic that, your application is pending or pending adjudication. USCIS will adjudicate all N400 in a timely and efficient manner, we will not tell you a timeline of when the process will be completed. We will let you know if additional evidence is needed or any outstanding issue is to be resolved with your application. Also, true the case processing time from USCIS website is still 2 months away. They are currently processing for this field office is still November 2018, and I applied my case on January 10, 2019. Any similar experience and what was the outcome?
