How is "gl" symbolic of love or romance?

So I am thinking of having a wedding around the theme of "gl." I have always loved the visual and aesthetic properties of gl, whether it is a work of art or a window...but I would like to connect the theme to my wedding more directly. Does anyone know how the material gl might symbolize love, devotion, romance...anything wedding-like? I would like to be able to rationalize my theme with more than just "it's pretty" haha. Any love poems or reading involve gl and love, also? But most of all, if anyone has any ideas, metaphors, or examples of gl being related to love, please let me know! Thank you so much!!!!!!
