I don't know that you can. He's not ready to face it yet. It's no different than people thinking life insurance is bad luck, completing wills means you are planning on dying and funeral insurance is terryfying. Lots of people think like this. Just plan along love and get things sorted for yourself and let him stay in denial as long as he can. He will face it when the time comes and hopefully that is many many years in the future. My sister and her husband bought an ostrich farm not long before she died of bc. She was with him to start his dream and it has given him 15 years of joy everyday since her passing. Wise woman was my sister. I bet there was never any discussion she wasn't going to always be there with him. His step children worry that he still walks the 5km of fences daily at 85..his response. ..what a glorious place to die. Sneaky plans for life beyond our time here can help some I think. Kath x
