Greetings @Amara,
Thanks for sharing your candle spell! 
In case you haven’t seen it yet, I recommend checking out the Flickering Magic: Candle Reading Guide- it has lots of tips for candle divination 
As for post-spellwork Wax Readings, while I’m not a wax reading expert, I do a form of wax reading based off of Tasseography (Tea Leaf Readings).
While I always believe the spell caster is the closest to the spell and the most aware of the intentions set while casting (and thus, will have the best and most relevant interpretations), I would be happy to share with you the things I picked out while examining your wax spell remains.
Here’s what I saw!
Two figures (blue) - Two figures stand tall, one whose features are more defined and another whose features are blurred and shadow-like. The more defined person seems to have their hands at their face in a worried position.
→ As you cast a binding spell, I feel that this could be the person who has been affecting your boyfriend’s business. This “shadow” could be a result of the spell- a symbol of pressure, guilt, or fear coming to haunt and loom over them.
Embyro (yellow) - Encased within an egg-like bubble is an embryo, with a nearly fully-formed figure curled up inside.
→ Are they curled up in agony, haunted by worries and fear? Or is it something in rest, waiting to hatch- for better or for worse? I would ask you, the caster, to take a closer look at the details here and see how it appears from your more involved perspective.
These are just my thoughts- please feel free to use them if they seem relevant, and don’t hesitate to apply your own interpretations to the spellwork you cast! 
I hope my interpretations can help you a bit, Amara- good luck and thanks again for sharing your spellwork! Blessed be
