UPSIDE DOWN - still struggling, trying to detach

[Dudess]

I told him that if he didn't want to meet, then fine and where would he like me to have his mail sent. I'm getting SO fed up of all this game playing.

I'm not sure I understand the mail comment. Are you telling him that if he doesn't want to meet with you in person that you will have his mail sent elsewhere?

I think that it's about time for a very serious letter from me to H.

What would be the objective of that letter?

Just responded to his negative email - was polite but business-like and maybe just a tad mysterious.

I think the suggestion to be mysterious is about your personal life, not financial matters of joint concern.
