Thank you, I've explained to my husband they need to know  as hard as it is, they're not babies, they're grown men.   They know he has cancer but not how bad it is, and my husband is adamant to the point of saying to me I'll never forgive you if you tell them.  I think I've made up my mind to tell them, regardless of what my husband says.   After all, I will be rhe one left to deal with the fall out.  Its just so hard.  Thanks for your response, and best wishes to you x
