Don't really know what to say except I am so sorry for all that you are going through. My kids are all grown, it's the little ones that ask questions, and their parents have to handle them. I know my granddaughter cried when told Papa wouldn't be living here anymore. Broke my heart for her. The older grands stay quiet, but you can see it in their eyes.
Your daughter sounds very intelligent, very thoughtful, and very sensitive. You sound as if you are putting the feelings of your children ahead of everything else, especially yours. Know that your children will always remember that. Who their Dad is, and how he has cared for them.
As Antonia says, you seem to be a wonderful father, and you will find peace. ((HUGS))
