Dear friends, I have recently received your wedding message, and I am sincerely happy and excited for your upcoming wedding and wish you a happy and prosperous married life. I sincerely wish you happiness on this special occasion, but I'm sorry that I was unable to attend your wedding.
I know that your wedding is very important to you, and I want to be able to witness this moment with you, but I have some important things that cannot be changed to attend to your wedding. I'm deeply sorry because I was really looking forward to being able to attend your wedding, but due to work (or otherwise) I need to stay here during this time period.
Although I cannot attend in person, I will be with you in my heart. I wish you a smooth wedding and a wonderful memory. I will be thinking of you on this special day and I hope you can understand why I was unable to attend in person.
At the same time, I will arrange a time as soon as possible to find an opportunity to meet with you and celebrate your wedding together, and to bless and congratulate you. Congratulations again and I wish you a happy and long marriage.
Best wishes,
