Just did my very first petition, need some advice to get my ex back!

Hello!! I’m quite new to witchcraft but I just did my very first petition. This was to Duke Dantalion, and I asked to have my ex come back to contact me and apologize for what he’s done. I wrote it down on a notebook, tore the page out with his sigil, said his enn several times, and then flushed it down as water aligns with him.

I was wondering if what I did was okay. I trust that he received it, but I’m hoping that it was alright. I also wanted to know if I could contact Sallos aswell?

Additionally, I wanted to ask if I could petition Sallos and Duke Dantalion for the same thing. Or if it would be better to wait until after Duke Dantalion finishes my petition (within 2 weeks!)Thanks everyone!!
