Calm down
you worked for 5 years continuously from 2007 - 2012
Working or Self employed ?
Do you have all 5 years P60 / Payslips? if working ?
if self employed Invoice/receipt/tax records ?
If yes then you are already a permanent resident in the UK and you are eligible for British citizenship. And you don't have to worry about EEA2 ( family member resident card ). Even if he never had that EEA2 he would still be legal resident in the UK as a family member of an EU national
When you both got married and how long he living in the UK ?
If he is married for 5 years ( if married in the UK ) then he is eligible for Permanent residency
If you married outside the UK then he is eligible for PR 5 years after arriving in the UK
