I hope he will pay you. He has maybe internet problem or .....
Next time , do it step by step , for exemple you send 500k, he pays you , you send another 500 k, he pays you.... More fees but you will loose less if the buyer doesn't pay you...
Another way would be to use an escrow like this https://coindaddy.io/services/asset-transfer-escrow   . (I have never tested it) (correct me if I m wrong)
Becareful, many thieves on internet (I m not telling you ronny is a thief )
