No, Dad gave it to you of his own free will. Your bf did not give it to you of his own free will. Why did his Dad do this? Did his dad have the right to do this? Was it dad s demo to give? *This all being said, it would not be your responsibility if Dad did violate boundaries, after all, that was Dad s free will*. But why did this all happen without the boyfriend seeing? There is something funny going on here. Why does he not want you to hear him sing? This is really the crux of the matter, and what you need to be talking about. What is going on that he does not want to share with you something so important to him? I think he knows that this voice is not his strong suit. I think Dad agrees and is hoping that YOU will say something so he does not have to.
I think the most important two questions are 1: why does he NOT want you to hear him sing? Have you asked him this? What did he say? 2: How do you think you can tell him this without hurting his feelings? Is this even possible? I understand you want to tell him. But you will have to figure out some very gentle way to tell him. How would you feel if your loved one did something you had made clear you did not want him to do, and then told you that you did this thing you did not want to share with him badly?
I think you should encourage him as much as possible. When he asks for your opinion, you should give it.
Good luck--this is a hard situation to be in.
