Princess, that does make sense, I'm afraid, even though it sounds very odd. Epilepsy is the tendency to have recurrent seizures, rather than a defined illness like, I dunno, diabetes. If someone carries on having seizures = they probably have epilepsy. If they don't they probably don't, IYSWIM.
Lots of things can cause seizures - high temperature, for instance - so one or two seizures do not mean someone has epilepsy.
Must have been very scary for you, I do feel for partners as I think it's probably worse seeing someone else having a seizure than having one yourself.
