Adjustment of Status - I-485

I had my I-485 interview yesterday and the IO was awful. My husband a US citizen petitioned for me and He was questioned to the point of where he almost had a nervous breakdown. She was so angry and aggressive. It's like she took a sudden dislike to us. My questions and answers went well but he was a wreck. We have known each other for 6 years and got married over two years now. We had all that they asked for and she wanted to know how I got a bank account without a SSN and why my name was on the Lease agreement with the SSN also. She even wanted to call my Lease Agency. Why my husband and his ex-wife did not have any children. She also said that she is going to request transcripts from IRS. We were in there for a little over two hours with that lady. At the end she asked me to sign the document and said that we will hear from her in the mail. We did not get a letter or paper with anything. Did anyone ever experience anything like this? And what happened next?
