I would want to checkout because of the topic of discussion or a particular person and the feelings talking about them were causing, not because of what was going on with me and my therapist. As much as my parents loved me, and tried to show it (still today), it did not lead to safety and security growing up, or as an adult. I'm quite lucky that my therapist figured out how to help me heal my past, and feel the love (still in the same way), offered by my elderly parents (~80 yrs). Today, I understand many times they meant well, but they missed the boat big time back then, and none of this makes them bad people. I was able to mourn my past, and move into a much satisfying today and future.
