^^ agreed, maybe the boyfriend was all wrong for her.
'see through the veil' i'm guessing she's strengthening her clairvoyant abilities and is trying to sound mystical. or she's just messing with you, or something else.
keep in mind faeries are tricky creatures. they seem pretty, magical, and nice, but cross them and they'll get you back. so just double check you cast it correctly. i'm sure you did, but just to be sure.
finally, you're not a horrible person, if you accidentally cursed your friend [which i really doubt you did] it was an accident, not intentional, you're not a horrible person for making a mistake, it happens, we all screw up something at some point in life.
