It is really inconvenient for a friend to have a wedding and a person to go back to have a wedding in a different place. You can tell your friends that you are too busy to come back and no one will arrive. I believe your friends can understand you. You can be called friends because you have a deep friendship and know each other better. He knows your personality and understands that you don't go to his wedding.

So don't get too involved. If your friend will be angry about it, you can only say that your friend is not sincere enough.
