Zen888,
I'm sorry for the shock and grief you feel. I wish things were not the way they are.
Burn-out is not something anyone plans on having. It can take tremendous energy to be someone's caretaking family person.
Burn-out can't just be willed away or wished away. It is exhaustion at an emotional, mental and physical and even spiritual level.
I think you need to accept his need to take care of himself for a while and see if your T can help you find other means of supporting yourself for a while. If you let him rest now, he may be able to come back. If you don't honor his need for distance now, he may never come back to the relationship. Burnout is real.
I know you need support, but you also need to deal with your life and not just go into hiding and sleep your life away - that will eventually mess things up badly. Get in to see your T and begin to work on your plan for recovery. Keep coming here and we will support you as best we can. I do care, but I care enough to tell you the truth.
