I don't think that your loved ones don't care - they just don't know what to say or how to act. They may also just be trying not to think about it (which is small comfort to you).
I was diagnosed with bladder cancer a couple of years ago. My cousin (who had previously told me that she considered me to be like a sister) only got in touch with me about it after I had been successfully treated for it (many months later). She was crying and genuinely upset, and told me she just didn't know what to say to me before. Which was fair enough, I thought, because I hadn't really spoken to most of my family about the cancer because I also didn't know what to say!
I also think isolating yourself from people you care about can be a normal reaction to grief and stress. People will get in touch with you when they are ready. That said, I agree with SamR, ask for help when you need it.
On another note, really great news that your husband is recovering well!
