Dealing with an ex-husband that was at fault in a major car accident?

Recently, one of my children was injured in a car accident and we have since found out it was due to my ex-husband’s carelessness. It’s been a tough week, to say the least. My ex approached me and asked that I “smooth” it over with the police ask me some questions. (still can’t figure out why they want to talk to me, I wasn’t here. We’re in Florida, right now.)

I don’t know if they are looking for me to say that he is some reliable guy. I can’t say that he always is reliable. He has moments of glory, mixed with moments of idiocy. I’m not going to sugar coat things for him.

He’s pulled the injured child into the mix, which is highly wrong, to me. The child is on the mend. As far as I’m concerned, hands-off, should be the rule.

I’m trying to remain calm with him around, it’s not easy, but tomorrow could be worse. My husband and other child show up to visit the one in the hospital. I know the word tense comes to mind.

How would you handle your ex. I’m trying to be civil. While I now know it’s his fault, it’s not like he wanted someone to get injured. Much less someone he loves. I’m trying to keep my cool, but all bets are off, with my husband.
