I'm writing a journal in Latin to practice my knowledge and I came to a thought which I'm unsure of how to render. I wanted to write: "I don't remember if I told you why I did that". My rendering would be:

"Non memini num tibi dicerim cur id fecissem".

I'm following here Gildersleeve's grammar (511, note 2) that states that the primary senquence shifts to secondary sequence when double dependency is involved. I'm I following the rule correctly? Thanks for your help.
