Adjustment of Status - I-485

Hello family,
Pd 5/16/16
First interview 1/17/17
Second interview 6/2/17
Married 2012 to citizen
We've both been married before.
We got there with our two lovely kids, our interview was 8:30am got sworn inn, the officer was nice, he opened the folder and told us he was going to direct questions to me but told my husband he was free to answer any if he wishes.
Just basic questions but mostly from my ex husband, why we got divorced? I had to narrate my whole story, who filled the divorce?(apparently my ex filed for divorce) when we got divorced? (I was my ex 3rd wife)
HE ASKED WHY DIDNT YOU REMOVE CONDITIONS ON YOUR GC?
I TOLD HIM I DIDNT HAVE THAT KNOWLEDGE THAT I WAS SUPPOSE TO REMOVE CONDITIONS.
 He asked this same question twice...

When I met my current husband? how many biological kids I hav? With names and birth dates...it was a lot of questions I'd say our interview lasted about 30 mins..
He was done and told me answering those questions makes everything easier than going through the big folder, he told me he was done and asked if I wanted to add anything, told him no. He printed a sheet of paper asked me to go through it, "it was all the questions I had answered" asked to sign it if everything looks alright.

I asked him if I was approved, said no...
he stated he will send the sheet of paper to the head office then I'll hear from him, he also added he will do his best and i'l be getting a response soon.
My husband was not asked a question, he asked our daughter her name," in a joking way"

We were not separated, called in same time left same time.
What do you guys think about this experience?
It's a little nerve wrecking...
plz share your experiences,
What's the worst that could happen to me?
I've had a headache since I left the office...
