I think I understand why you want this oppurtunity and I say GO FOR IT !!! You are right ,YOU have done nothing wrong . Putting your questions out there and confronting them with them can give you closure ,because you will see they do not have God behind them or truth . You really don't know this for sure until you give them the chance .
You already said you have no JW family ,so no problem there . As for 'friends', you will find in time they will avoid you announcement or not ...the ones that still have contact with will feel obliged to 'encourage' you back into activity . So I think for your own peace of mind go ahead with the discussion .
You have been warned of all the consequences ,but only you know what benefit will be derived personally by going through with this .
Good luck
