How do you propose rattling her [my bf's mom's] cage that will make an impact sufficient change her behavior bring the two of you closer?
I have no desire to become closer to her. To put it it cobra-speak: "where did you get the idea I wanted to be closer to her?" Our relationship is just fine the way it is.
No one can change anyone else's behavior. If anyone on this bb has proved that, hairdog has. They don't have to D. he can go about his business, live his life while they are under the same roof. He probably won't, because he's a type 6 and Loyalty is their strongest trait. But he could. He could just start pleasing himself and devil take the hindmost.
