How can I show her how much I lover her?

Dude simply just tell her find her alone set the mood on a date or something but if you have love that deep she has to know better her knowing your there and your out there waiting for her seriously if you don't tell her that's a crime of pion this is what I would do wright that poem on paper tell her how you feel about her and give her the poem but tell her to read it when your not around to feel more misterious
