Husbands diagnosis

Just wanted to post about my husband. He got diagnosed with a brain tumour in September 6 weeks after getting married - no symptoms went to a&e for something else and they found this. It's been a complete rollercoaster since with him in and out of hospital, appointments etc. Yesterday he saw the surgeon who said they had removed 98% of the tumour and was now referring him for radiotherapy & chemotherapy but that these tumours always come back but couldn't say what time scale it could be 6 months it could be 2 yrs.  We came home so distraught as we feel it's a ticking time bomb ! We met late in life and have been together 2 1/2yrs and had so many plans for our old age and I feel now at 50yrs old my life is empty. I'm so scared of losing him and what life will be without him in it, it took me so long to find him and now he might be taken away . I'm watching a strapping 6'3" farmer who did everything to a man who can't speak well, has lost weight and passion for everything. I'm not sure who to turn to or what to do.
