Thanks for reaching out for help. From your history, it seems there have been various attempts to go for counselling and they have not been fully successful. I would encourage you to try once again to take appointment with a counselling psychologist.
Next Steps
If you feel your spouse is not opening up, you can approach a counselling psychologist who can help her be more forthcoming in her discussions. It is only after she is comfortable talking about herself can you go into couples counselling. I would suggest taking online appointment with someone like me who can also use NLP and Hypnotherapy to help her deal with childhood problems, if they are present.
Health Tips
Your wife and yourself need to be first on the same page regarding taking psychological help and working out your issues. Rushing into divorce proceedings might not be the ideal step now. Do strive to get her to co operate for in depth online counselling sessions with me or any therapist if your choice. It would definitely be beneficial.
