So @CJCW17 you have a six month window to tackle some things before you complete your studies?
Being practical, I suggest that you get in the booking list for Relate now as it may take some time for an initial assessment meeting to come up. If the appt comes up & he demurs, then go for yourself to explore how you got to this stage of your life - Relate is about relationships, not just couples.
Also, draw up a schedule of what needs doing : divvy up tasks & make sure that his share can be done as & when he can with the expectation that he does one task per day…no more. This is the first stage. Get this started with a reasonable daily task. Don’t question or argue when he doesn’t do it or doesn’t do it perfectly, you are not his mummy. If he doesn’t do it, so be it the task is not done & you don’t do it. If his depression is so overwhelming that this relatively small demand is too much then this is another indicator for going back to the GP.
Recovery from depression does not come to the door, it can involve undertaking small daily tasks - just one a day at first - to make progress.
First get out bed. Then do task…
Ring the GP as the patient’s wife & IN CONFIDENCE share your concern that he is not progressing on the current meds AND that although he has agreed to consult further with GP he cannot/will not do so. Also that he seems not to have picked up on the therapy referral. Make sure that you say that his inability to tackle & take responsibility for his own condition & recovery is having a detrimental effect on the family & your health. State that you are at the point where this call to the GP is the last thing that you can do. No more. Any more for him & you will loose your self. Say how much you are doing for him.
The GP will maintain patient confidentiality & that does not bar or exclude taking account of your concerns. If you share the same GP, then still ring to voice your concerns.
GP may instigate a review of his prescription - as is/was usual for repeat prescriptions &/or invite him in to discuss his progress. If he has an illness, he needs to get better or get his finger out as he has a life to live & adult responsibilities.
So, in the past even when he is fully engaged with work, tasks & childcare, you would still be spinning plates behind the scenes? This is something to do with you asking for what you need rather than just settling for some love, & learning not to fix folk - you can work on that with Relate if you go on your own. You already have insight into your family dynamics & with some specific therapy for you about how your past is echoing through your family life now, you may make great strides.
For the next six months you can work on putting yourself first, it takes some practice. By the time your studies are over & you have made some changes by doing some things differently (e.g. not fixing, letting go of tasks, easing up on perfectionism) then if your OH is with you, you may have a better idea of where you are as a couple & where to go next.
Put your self first.
