We all know men handle things differently than woman do. I am a 48 year old male and have few in my life that are close to me. I was given the cancer sentence in the spring. I started my journey alone and not letting anyone in. I don't like to impose on others and just figured I can handle it all on my own. My partner wants to help, wants to be involved and well this is all new to me. What I found with him and my small group of friends is to let them in to my life. Believe it or not they want to be involved and know how I am doing. Seeing the feelings of others did tell me I wasn't alone and with that when someone did show concern or sadness or tears, it helped me to realize that people really do care about me and it gives you a "kick in the pants", if you will to move on and get better. Regardless of what your husband tells you, seeing your emotions will aid him. We, meaning men, are taught to go things alone, take care of those in our lives, be strong and just go on no matter how we feel. It takes a spouse or a partner or even a good friend to show us that isn't always the best way to be.
Good luck with his care and I wish him every option and chance for remission. Try to be yourself and do what you think he needs; I doubt he'll tell you what he needs or wants. Sometimes just saying, "I can only imagine how you feel" and some human contact by quietly touching him or just hug will give him more medicine than you can imagine. We're tough on the outside but we can be soft on the inside, especially when we are scared. I have this tough-man exterior, but inside knowing and seeing those that care about me let's me know if I wasn't around I really would be missed.
I hope this helps some. There is no right or perfect answer to give you. Follow your head and heart and watch how he responds, that'll tell you the path you should be on to aid him.
