Sorry if you don't like what I
am going to say ...

Try to make a deal with him --
contribute some to the family
of you two by every pay check;
and set a quota that you can
use freely.

By so, you will manage what you
and family of you two deserves.

Don't tell him much about your
expense, and don't ask much about
his expense.
