@Shaz51. In one way it will be hard for your husband to hear he has MDD. On the other hand, once you have a definate diagnosis, then a level of recovery therapy can begin. But it must be with your husbands consent.
I wonder if there is a group that does therapy for Depression. Or a male Group with a strong emphasis on positive steps for looking after your health. If it had a strong male leader, I wonder if that may help your husband chose treatment with a psychologist.
Just rattling off random suggestions.
I agree with @Former-Member. I too have MDD. Struggling at the moment. Am takng twice the maximum recommended dose of my anti depressant - not working. But that's all the psych thinks about - more meds.
My psychologist says I need to change my thought patterns. In the past, after my first depression and hospital stay, I could successfully do this. But with my current episode now into it's 17th month - it's a struggle to change my clothes let alone my thinking. My negative self talk is so loud.
No groups in my area of the state. Only can do groups is to go to hospital.
I do hope your hubby is able to find the motivation soon for some sort of therapy. Hugs to you both.
