thanks for clarifying issues and for your further update.
I can see that you can communicate with each other and you both listen even if the answers may be uncomfortable, The fact he is wanting to see the psychiatrist and go to couples therapy is really encouraging because many people are reluctant to reach out. You are also ready to listen and to express your feelings.
It is good that you are gaining more insights about his way of communication and the effect anxiety has on him and how he expresses himself.
As I have said before your posts help others and I find I am learning how even in a complex situation there are ways to find out more.
I think with counselling over time you will develop more skills and be able to use them outside therapy.
You are recognising more what is happening in your relationship and even if it is upsetting you are understanding the role anxiety and depression plays.
Thanks again for sharing .
