Meeting ex husband at 5 today

We were married for 21 years. We never caught, no one cheated, it fizzled out. We said we would be civil and kind for the kids. He took me for a fool and hid hundreds of thousands and got away with it. I spent 34k as a teacher, trying to combat his high powered attorney. Today he wants to meet and reconcile. I agreed but I’m only meeting to get him to agree to equalize assets or I’m taking him back to court. Advice quick! Help!
