There seem to be a lot of questions around this subject, but couldn't find one specific to my case, so would really appreciate any advice or feedback.
I am spouse of an EEA national and we have been living in the UK (I am neither an EEA nor a UK national). As the spouse of an EEA national, I hold a resident permit in the UK and also have a short-stay Schengen visa.
Over the next 5 months, I would be traveling extensively to various countries in the Schengen region and will quite likely end up spending over 90 days.
During this period, I would be traveling back and forth among those countries, traveling back to the UK, but would largely be based in Italy.
Does the same 90/180 rule still apply? If so, how strongly is it checked across borders of different countries? Can I apply for a visa under a different category - may be a business visa, to stay beyond that 90 day period?
