Hi confusedpartner,
Welcome and hello
It's so tough when the help is there and they won't take it. It must feel so confusing and frustrating and sad. And on top of everything, you have three kids and are in a graduate program. You have a lot on your plate.
There are communication skills that can help mitigate the conflict, and members here have lots of experience applying them. We can walk alongside you and support you as you pick these skills up and practice them.
What are some of the behaviors causing problems for you at the moment? Maybe we can focus in on one thing and start there.
What happened 3 years ago that led to his diagnosis?
Glad you found the site and hope to hear back from you when you have a chance and feel comfortable telling us more about what's happening in your marriage.
