When considering how to write a love letter, it is best to speak in a language that the heart already knows; love. Before even thinking about putting pen to paper, you have to put yourself in the right head and heart space. Find yourself a quiet and distraction free spot and get comfy. You may want to bring a pen and notepad along with you for this bit.
Once you’re settled, close your eyes and begin to bring your focus to your fiancé and all the things you enjoy about your relationship with them. Pay attention to any thoughts, words, feelings, or visualizations that come to your mind with ease. These will likely be the starting points and themes to draw from when writing your letter.
The goal of this exercise is to really narrow down and identify your own feelings so that you can articulate them in your letter. You want your fiancé to be able to feel what you feel while they are reading your letter. If you can’t make sense of your feelings, chances are, they won’t be able to either.
