I am glad to read that you are sounding stronger. Because I think you will need that strength. After reading about your H's latest and that text I share NLT's concerns.
This sounds beyond MLC drama and it sounds like this is greater than simply a marriage issue. This sounds dangerous. Now you do know your H well. But it sounds like he needs assistance. Dawn is there anyone you can refer him to or any resource in your area that can assist you in persuading him to get that help?
I recognize that you cannot force him to do anything or go anywhere and I absolutely understand how you fear getting involved. But trust your gut and if it seems that his behaviour is beyond the drama, maybe seeking help as any of us would for anyone truly desperate may be in order.
I feel for both of you. Not any of us should feel like nothing matters.
