If it makes the asking easier for you, call them up yourself without informing your husband. You can keep the call brief, and you will have the element of surprise in your favor to make it a quick, simple 'how are you, get better soon' call. I understand. Especially your mom's hurt. You will find a way to deal with that memory without making yourself bitter. Time. You will also find a way to separate that from other more pleasant events and milestones of life and married life.
