First of all, nothing I've done has had a positive impact on my sitch at all. But, here are a few "mysterious" things from the last couple of months that should have worked:
I didn't allow H's regular Saturday morning visit with S because I told him I had plans for the weekend. He tried to move the time but I told him the plans were for the whole weekend. I told him someone was staying with me (someone was). We never had guests before besides his parents. He had to wonder who it was (but he didn't ask). I shared no details.
Reluctantly, I divulged that someone was coming over to help me and S cut a Christmas tree, that it was a planned event. No details from me, no questions from him.
2 weeks ago I had a home appraisal scheduled for Saturday afternoon. I told S(3) a man was coming over later and he asked what his name was. Sat. morning H arrives for his visit and S says "David is coming over". I was upstairs but heard H questioning S on who David is. Since S didn't really know, he got no answers. Later H brought it up again with S in my presence. Then he asked me "who's David?" I said "Just a guy". This was the first time he's shown any curiosity at all about anything I'm up to.
