Different types of care giving, next phase

My mother had been ill for about 6 months or so.  Several long and difficult hospital stays and rehab stays, ended just recently in her death.  During that time care  giving was visiting her for long difficult hours, being the go between with doctors and nursing and other family members and keeping my Dad company.

 She's now passed, the funeral a week ago.  And now, the next phase; looking after Daddy.  He's 83, pround and lonely.  He lives alone, physically is in good shape; but he and Mom were married 61 years, so he's not at all used to being alone.  They did nothing separately.

To help me with missing her, remembering her before all the troubles, I've started blogging tributes in alphabetical style.

That helps me, but....how to best help him without him feeling he's losing his privacy and his independence?  Mom took care of the bills, the taxes and things of that nature.

Thanks
