Good one gone!
Yes, it's your fault. You did all the right things in the beginning that made him/her fall head-over-heels for you then you stopped. In the palm of your hands you had a man/woman that would've had your back, defended you-right or wrong, been your best friend, talked to you about everything, stayed by your side in good and bad times, and loved you with every fiber of his/her being. You didn't appreciate him/her. Instead, you took him/her for granted. You let something get away that most people have been searching and wanting for years. Sadly, it's going to take someone ten times the effort now to restore the heart of the good one you made walk out of your life.
