Get in his own bed and stop being on egg-shells. ITs not about me, but I've had plenty experience in the WAW realm. He doesn't have to respect her all the time, we can guarantee she doesn't respect him all the time.
What I proposed was not mistreatment, it was not violating her space or anything. Its his wife, and his house and his bed too.
Walking around the boundaries she's allowing, doesn't seem to be working to me. Eventually the dynamic needs to be changed.
By the way TrentC, she needs to earn his trust - not the other way around.
