Booking a spell as a Christian?

So me and my ex broke up a month ago. I can’t get him out of my head and keep running behind him. He claims he still loves me, but less but just wants to be alone.

Through social media I booked a ‘come back to me spell’. This was an impulsive decision, as I want to do anything to get him back. I told her that I’m Christian, and she reassured me that she only uses angelic & devine energy. I already paid the money. She doesn’t to refunds, but I don’t really care either. She told me she will do the spell the 22th. Now my question is can you go through with this spell as a Christian? Because I can still tell her to not proceed, although I paid the money.
