I am Gala born 14 July 1960. how to improve my relationship with my husband born 27 Nov 1953?

I am a rat woman married to a horse man for the last 30 years. We were very much in.love but have drifted apart. What can I do to improve my marriage? My two grown up children live in a different city. We are now alone as a couple and I would like us to be close once more.
