Grappling with log-jams in eft work with couples

Of late, I have been struggling to work through negative cycles highly resistant to change. In particular, I have begun to focus upon the "key shift" that each partner needs to make that would allow them to feel less defensive/threatened by their partner's behavior. With this in mind, I have begun to explore following up the eft sessions with brief individual phone sessions, with this or that partner, specifically to further tease apart and unpack why they continue to feel threatened by their partners behavior.
