How can aura cleansing with fire affect emotional blockages in relationships?

I recently burned a letter that my ex gave me because I want to remove him from my life. But, I instantly cried. Was this some kind of effect of aura cleansing with fire? Is it actually me letting go of all the previous emotions?
