Is having spirit attachments the reason for my client’s husband’s negativity and lack of affection for her as she described to me? What can we do to help?

What is happening is that the spirit attachments present within him are triggering old karmic business to generate strong negative emotions and fear-based thoughts about having a life partner. This is not peculiar to her as a person, but simply being in that role. She is seen as the icon representing spouse or life partner, and thus has, inevitably, become enmeshed in the swirl of karmic forces being triggered and reawakened by the spirit meddlers knowing it will throw him off balance and create an energy demand. That is their game, to make their host miserable and call forth greater energy in a plea for help, so to speak, as it helps them indirectly, being parasites only surviving at the expense of the living to provide them energy. We see that a clearing done for the both of them will help stabilize things. The karma still needs to be worked on, and that will take time, but meanwhile doing a Lightworker Healing Protocol session on the two of them is the quickest way to get help started.
