Not to speak for GH (because he certainly CAN do it for himself), but he really isn't being assertive/aggressive or otherwise with you (in fact, in my experience, he is likely one of the least aggressive individuals on this board). He merely is trying to re-focus your efforts onto what is important here: namely, your self-improvement. Identify those things in YOURself that needs improvement and work towards that. Come up with some ideas/goals and work towards them.
I'm not completly up on your sitch, but I will do so and provide whatever input that I can in the future. In the meantime, think about some of the things you have learned and put them into practice.
All the best,
Rob
