It sounds to me like you pushing your wants. You have already looked him in the eyes and told him you loved him and want to save your M, correct? Do you think having his good friend there will change his mind? Has something else indicated to you that he is unsure where you stand and just needs confirmation to come home?
You said one of your 180s was active listening, correct? He's told you directly to "leave him alone". Would getting on a plane to fly out to confront him face to face show that you are trying to listen to him? Will these actions in someway validate his feelings or is he just going to say again "why wont you just leave me alone"?
I'm not a vet and have seen no success in my own sitch so feel free to ignore all of this
