Either way, none of this is really relevant to the OP, since she has only been in the UK for a few months and won't reach 3 years of ordinary residence in the UK for another 2.5 years... by which time she may well be 'settled' in the UK anyway (depending on the rules for probationary citizenship, since ILR will no longer exist) and/or the home fees rules may have changed by then.
I've always been under the impression that unless you are classed as a 'non-EEA family member of an EEA national' for immigration purposes (which the OP isn't), then you cannot qualify for home fees unless you hold ILR as well as being ordinarily resident in the UK for 3 years. Maybe I'm wrong, but I've been a member of this site for 3.5 years now, and I have never heard anyone say otherwise in all that time - even when I've posted on other threads regarding being eligible for home fees, not once has the 'family member of an EU national' category been brought up in relation to whether the spouse of a UK citizen is eligible for home fees.
Does anyone have any examples of someone married to a UK citizen being allowed to pay home fees when they did not hold ILR? I haven't heard of it happening, but maybe that's because the majority of people on spousal visas will gain ILR before reaching 3 years of residency, so it's a moot point because by then, they meet all the criteria for Category 1 anyway.
