I have concerns regarding my ex’s driving while my children are in his car. They have only in the last month started spending time with their father, after 6yrs. The other day they brought up that he speeds and acts like a hoon, my son had told me that one time that Dad was coming sideways into his driveway and my son hit his head on the window! Their Dad and I have a very volatile relationship I am wondering how I approach him without starting conflict. How could I have him listen to my concerns without disregarding anything I say?
