It depends how much your deductible is.

If you already spent $1,100 and your deductible is $500, you’d be spending $1,600 altogether because they won’t refund you for what you spent. On top of that, the insurance company is going to put you at fault because he had the right of way which guarantees that your premium will go up.

If you spent $1,100 and your insurance is $1,000 don’t contact your insurance whatsoever. Not even to inquire because they can still raise your premium (albeit less) with this information.

Regardless, it seems like his car is fixed and he’s being a douche. I would keep the receipts from whatever you spent and tell him to see you in court if he wants more out of you.

The other alternative is to pay the other $1100 but to me that’s excessive to pay $2200 to fix his car with the amount of damage you’re describing. I highly recommend telling him you can settle it in court. I don’t want to see you get taken advantage of.
