Interview after I-751 filled alone (divorce) but affidavit from ex wife and family

[armando]

I divorced only 8 months after getting married with my wife in the US, we are still friend and the marriage was in good faith .

I have submit the I-751 by myself last year and today I just received a notice for an interview. I have submit the usual evidences( bills, lease , bank account etc...) not more or less than the average person.
I am really afraid that my case will be denied and I am trying to to be optimistic and reassure myself.

My ex wife and her parents will send me an affidavit for the interview to support me. Plus my ex wife was in the military .
Does any of the factors above are big asset for the interview or it wont change that much ?


Thanks
