The man is lying to you, and it appears has done so repeatedly. He told you to disregard your family's concern for you, even though it is creating strife in your home. Therefore, your feelings have not been a consideration to him.
I am 100% against ghosting. In the majority of cases, I think it is rude, disrespectful, and cowardly. However, in this case, I am concerned that if you have a dialogue with him, he will only have a chance to be manipulative and convincing enough for you to continue to stay with him. As someone who has experienced domestic violence, what else besides a domestic violence record, and lying about the same, would a man have to do in order to convince you he doesn't have your best interests at heart?
No, I'm right in line with your friend. He had the opportunity to be honest about his prior conviction, and chose not to be. He's disrespected your family. He does not respect you. I feel like ghosting is appropriate in this situation.
