Marriage question for Ox and Dragon

Hi
My husband and I have been married for 5 years and we have 3 beautiful children. Our marriage has had great times and some hard times. We're currently distant and strugglinG to connect. He was born on 2/5/1986 and I was born on 10/01/1988. We're compatible in astrological zodiac signs but not in Chinese zodiac... Can our marriage still be harmonious despite the incompatibility? If so do you have any advise on how to keep a peaceful happy marriage
