Hi,
I got Regimen Comunitario tarjeta by marriage. But I don't live or work in Spain or any EU country.

1. What is the maximum duration that i can stay outside Spain without losing my Regimen Comunitario residency?

2. And what if i exceeded that duration?

3. What if i exit from another schengen country so that the spanish airport will not check my passport/tarjeta and will not update the exit date in the spanish authority system?

Thanks.
