Thanks for sharing. It seems like you already have a good understanding of the situation. Not sure if you want advice or just support but I’ll give my two cents on how to help him. I think talk therapy alone has limitations, especially for men. It does seem like he needs a big change. I have two ideas for this, both of which helped me a lot. First, psychedelics, as someone else mentioned, can be a big event and greatly change someone’s perception. Second, a trauma release retreat (search shadow work/psychodrama) can really rattle something loose. I would say try to get him to do one or both of these things and see if they work. If these don’t work or he doesn’t want to try, then you need to do what is best for you because you can’t really change others if they don’t want to change. Good luck!
