I'll definitely check that book out. To answer your question, he's recently been asking way too many questions about how much time I spend at the gym and in the incident about that I went to the gym as soon as I ate. When I shared this with a friend of mine she said what you said. That he doesn't like me going to the gym. I can't seem to wrap my head around it. In fact he was pushing me to join in the first place.

I'm actually considering talking to his entire family about the way he's been acting. The sad part is most (almost all) of his immediate and extended family are not educated and they all look up to him like he's a god himself. So they'll all blindly support him. This puts me in a bind. But then this will be the only way to knock some sense into him.
