I am very sorry to read about your husband. My husband passed away two years ago. He had two GBM tumors. The doctor did not remove them because he said they would just grow back. My husband did some brain radiation and Temodar. He was on Keppra also. The brain radiation killed him quicker I think. I’m sorry I don’t have more encouraging words. All I can say is just try to enjoy every day with him. Be supportive. Don’t get upset with him. Tell him you love him every day. I wish you the best.
