Assalmu Alaikum
(Look, not everything should be considered as (Hasad or Sihr
Some times words play a more important rule.
You should talk to your husband and let him open his heart to you .. maybe he is overthinking
about an issue or somrthing .
Also my advice to you is Dua'a, Dua'a and Dua'a ... the most powerful weapon for a believer.
and give your husband a book or a CD about the problem.
"Make "Sadaqah
in intention of Shifa'a.
May Allay Bless You and Solve all of Your Problems and Suffering*
