I'm glad he does know and I can understand one one hand, especially with not knowing the biopsy the results puts things in limbo and grieving still in the process. This is also you now and I can see why you feel alone, but he's hanging in there in his own way. I'm here, feel free to PM me. You'll know soon and can take steps from there to do what's right for you and your care.
Sending good wishing for negative results!
