Meet in a public and neutral place. Restaurant, coffee shop, something like that.

Try to keep your emotions in check. Make a list to keep on point of things that you need to discuss, and have the list out on the table. Set a time limit, i.e. you have XYZ to discuss, and you only have one hour. At the end of that time, leave.

Do either of you have an attorney? If need be, meet in your attorney's office, with your attorney, or one of the clerks, present.

Good luck. You will get through this. Breathe the fresh air (despite the pollen ) when you ride.
