I feel like it would be a good idea to have my socially anxious fiancee to have a wedding.
Why are you going to force him to have a wedding?
I mean, I just feel that if we are going to get married than we need to have a wedding.
There's no real reason to force him to have a wedding if you knew that he was very socially anxious. You could both have a great wedding with just yourselves and close family members without having the huge fuss.
I'm sorry if I don't feel the same way about weddings as you do.
It is wrong to try to force your partner do have a wedding. You are better off letting him know that it would mean a lot to you to have one. Making it an ultimatum in a way is only going to drive you two apart.
