I finally went, by myself, to counseling. I needed to know I was not crazy for crying at the drop of a hat all the time. My husband was diagnosed with stage 4 prostate cancer (spread to bone and lymph nodes) 3 years ago. He also rejected me, no talking, touching etc. This went on for 4 months. I finally told him I couldn't live like this (we'd been married 53 years at that time). He agreed to go to counseling separately first. When he joined me with my counselor it was eye opening. He finally opened up about his fears, not wanting me to have to go through this, loss of manhood etc.
Even if he doesn't go I would go myself. You need to get your footing with the situation and take care of you.
