I spent the night in jail. Now, How did this happen…

RO and I met to talk about our separation contract. RO started to get belligerent and took a few swings at me. I tried to leave but he blocked the way. I held him at bay for about 10 minutes. I didn't know how else to end it, so I took a good swing and pushed him down.

I stayed around to make sure he was OK. He started talking and swearing at me. So I  left.
We both called 911.
The police came and we chatted for a while. I'm not sure why took me and not RO. So, I spent the night in jail.
At my arraignment, I was charged with 4th degree assault and released without bail.
On my way out, the jailer joked with me "Before you go telling anyone any I-did-hard-time stories, let me tell you that you spent the night in the nicest jail in the county, and that 4th degree assault is not a felony. "
I never felt unsafe the whole time was there. Worried but not unsafe. My cell had 11 other people in it. Everyone was clean and well kept. When I entered the cell, they quickly figured out I was new to this whole process. One of them helped me set up my cot. Then he gave me a short speech on cleanliness. There were no janitors there so, everyone had to help keep things clean.
The cot was not comfortable.
This is not something I want to go through again. But, kudos to the staff and inmates.
Now. More later on what I've learned from this.
