Are you both on meds? If not, I highly suggest medications. It's hard to provide support sometimes when you yourself are also depressed. You could ask him how best to support him. He should be in counseling too. You cannot be his only support. Does he have a network of support otherwise? Some therapists will offer sliding scale fees, depending on where you are located in the world, so it can be cheaper. Since he is working perhaps he can afford cheaper rates. Good idea to ask your own counselor about how to encourage him back into therapy. He really needs this, I think.
