First, my condolences.
Secondly your own psyche and the psyche of your boyfriend are important. John Legend's All of You is incredibly beautiful, but radically different from this:
Do not stand at my grave and weep
I am not there. I do not sleep.
I am a thousand winds that blow.
I am the diamond glints on snow.
I am the sunlight on ripened grain.
I am the gentle autumn rain.
When you awaken in the morning's hush
I am the swift uplifting rush
Of quiet birds in circled flight.
I am the soft stars that shine at night.
Do not stand at my grave and cry;
I am not there. I did not die.
Mary Elizabeth Frye

Great for burial. I have about six personal and 'passing songs' all inspirational and uplifting. I have set music to A Song to my Beloved and I also recommend When I am Gone Remember Me, both by me, and on the net.
I wish you God's Love and Fortitude at the current time. Much Peace.
