When it comes to women that have some sort of trauma in their past, I think it is more about keeping control over themselves. Marriage is supposed to be all about trust. The problem is that even though HD may be VERY trustworthy, Mrs. HD has LOST the ability to trust anyone OTHER then herself. So she has to effectively CONTROL everything in her life. SHe is not trying to control HD, she is trying to control HER own life. The last thing she wants is to be vulnerable, (because that is how the trauma probably happend). So her solution is to make sure she is NEVER vulnerable. Not sure there is anything HD can do to change this, this most likely will require massive work by a IC and Mrs. HD.
