Op, I gave you the most practical advice. There is no confusion here. If he is going the wrong path, you will be making him all the more determined by asking him, if you don't ask him, he will still do it if he wants to. You can't control him and don't try to. If he never intended then you having nothing to lose. It is not about moods here, it is the most sincere, most practical thing I could tell, because confronting and taking it up will lead you nowhere. I have had it and I told you from personal experience. He will become more vigilant if you start probing, better to shut up and let it die a natural death than keep igniting the flames all over again by confrontation. Once you start the process, it won't end easily. I landed in IL because of the same issue and still having a tough time getting out of it. I made the mistake of confrontation and have landed in hot soup because of it. My health has gone down, I have gotten fat - I have caused myself harm while he seems to be getting stronger and merrier by the day. And about the others don't even mention - guess their jealousy and ill-feelings towards me started giving results because I yielded to them. To add, I will tell you not to discuss this with anyone in your circle, whenever the thought arises tell yourself it is nothing and carry on.
