"Quiero que entender, pero no se, mi corazon"

i'd really appreciate the help:)
This is what I guess

"Quiero entender... pero no sé mi corazón"

I'm trying to understand / comprehend... but I don't know (I'm not sure) my sweetie heart.
"I would like to understand, but I can't, "honey""
" I want to understand,,, but i dont know my sweet heart"

coz Carino is sweet heart

and cielo is honey

Carzon is my heart so the best thing to say is my sweet heart

thats wt i think
