Anyone who has been in therapy gets it aka, us we are fellow travellers on a path to inner peace! Outside therapy people don't get it because they are scared to dig deep inside and see what they find within.
Our relationship with our ts are so important and probably the best relationship we will ever have with anyone so people don't get it unless they have been in or had a relationship like that.
I think they are missing out on something very special. I am sorry your husband does not understand Asia, perhaps he is frightened by the deep intense emotions that the termination brought up, I bet on some level he is curious about therapy and the relationship but another it scares him and its easier to not understand?
