I hope you are doing well. First of all, congratulations on your upcoming wedding. I was thrilled when I received your invitation, and I truly appreciate being included in such a special occasion.
However, I am extremely sorry to inform you that I will not be able to attend your wedding. I feel very disappointed because you are one of my closest friends, and I have always imagined being there to celebrate this important milestone with you. I understand how meaningful this day is, and I feel awful about missing it.
The reason I am unable to attend is that my daughter has been unwell for the past few days. Her condition requires constant care and regular visits to the doctor, so I cannot leave her alone at this time. As a parent, I need to stay with her until she fully recovers.
Once she feels better, I would love to meet you and your partner to celebrate your marriage. I am planning to visit you after the wedding and take you both out for dinner. I also have a special gift for you.
I hope you understand my situation. Wishing you a beautiful wedding day and a happy married life ahead.
Best wishes,
[Your Name]
