Return to UK

I am a Dutch national married to a British national for 35 years.
I moved to the UK in 1979 where I worked and brought up a family with my husband.
As a European citizen I didn't need a British passport so I never bothered.
My husband and I moved to Spain in 2002 but have decided to move back to England for family reasons.
I am really confused as to whether I would be allowed back after Brexit.
I am 60 years old so the chances of finding a job  are not good.
I have a bank account in the UK as well as a national insurance number and of course family ties.
I don't know how I stand legally at the moment and would appreciate some advice.
Many thanks.
