I doubt he would have kept talking to you if you had simply said:
RTGU: "I will not talk to you now. You may email me if you wish."
H: blah blah blah blah
RTGU: "I will not talk to you now. You may email me if you wish."
H: blah blah blah blah
RTGU: "I will not talk to you now. You may email me if you wish."
H: blah blah blah blah
RTGU: "I will not talk to you now. You may email me if you wish."
H: blah blah blah blah
RTGU: "I will not talk to you now. You may email me if you wish."
H: blah blah blah blah
As far as telling H your plan to see a L today, all you do is hurt yourself and help H by sharing ANYTHING about your L meetings with H. It is none of his business. NOW he knows that you are starting on the legal process. This will affect the strategy that he and his L take.
