When it comes to long love letters, this one really touches my heart:
My Sweet Lover,
From the moment I heard your voice I felt a connection to your soul. I can still remember exactly how you looked the day we first met. Your beautiful eyes captured my heart and your smile erased any and all doubts that I had ever experienced. When you opened your arms I stepped into your loving, kind embrace and knew that I was "home" right where I had always belonged
