Joh Please stop. Please. I beg you.
This is something that matters to me more than anything. I would do anything, even die over and over for a girl (such as @Ines; good girls like that are rare but they do exist) who wants to live for her husband and be his and only his. To receive someone's trust, to live for someone. That is something I wanted ever since I was nine!
The belt is a symbol, a very powerful symbol. Jesus Christ wanted his apostles to touch his wounds, because a symbol you can touch, a symbol you can feel with your hands is the most powerful symbol of all. The same way, when I get eventually married, I want words "I do" to be backed by something, something strong, something physical. Like the flesh of Christ, the belt is a promise, a promise of love.
