Then quite honestly you should tell him to back off. That it's not any of his business.
I did tell him not to get involved. But, he got this idea in his head that he is trying to help my H with his life!!! He kept saying this is not about me and my H. And I couldn't tell him to not care about H's life....Sigh. I have such a bad feeling for this. But now it's out of my control. I knew him through H. So, I don't feel like he would listen to me. He thinks he knows H better.
I almost want to tell H about this, but...I'd only make it even even worse.
