Yes, an appt. w/DB coach is a great idea. I'm sure they have a better grasp on this.
As far as when to initiate the WHIGTL talk if you do go that way, I was thinking that you could DB & not risk it until pretty close up to the D date to establish some good feelings between you.
The difference in having your L send a request & you doing it in person is the difference, no. Kinda like the difference between having a telemarketer trying to sell you something & an 8yr old selling Girl Scout Cookies, which one are you going for, do you think?
I guess the peaking is not overt, just that I'm not hearing much blatant "I'm finished w/ you" speak/actions besides w/you, yourself initiated. That's why I think Mopo's might work, or at least not hurt of done in the right way.
