I was going to suggest a ferry to Santander ( with car) and then take it from there.
But as you don’t seem to like your husband very much maybe that’s too much time together.
... I did the ferry to Santander (with car) and just 'ad-libbed' it from there. Ending up in Cambrils.
It was a very relaxing holiday. If one hotel didn't suit, we just drove on to the next.
Probably slightly more expensive than a 'package' deal, but definitely more leisurely - and interesting, as we diverted off the beaten track into more remote villages.
In fact, I vowed I'd never do another package holiday, and never did. Although circumstances prevented us from repeating the trip.
But I'd recommend it. And the ferry trip (Brittany Ferries) was quite nice, too.
