Should I keep hope in my heart that we can be together again

I am a male born on 01/08/1963 and my wife (separated) born on 29/09/1966. I have looked at the Chinese Astrological compatibility (Tiger and Horse) and see a good match but with Western astrology (Capricorn and Libra) it is hard work. We have been separated for 6 years, by her choice , but I still love her and would love to be back together with her. She is a beautiful woman with a kind soul that loves harmony. We have 2 children and I despair at being separated. I want to build a secure life and future for her and our family but have failed in my efforts so far. I still believe that I can do it, but it will take time.
People tell me to move in and there will be a better match.
This is very emotionally difficult for me but I do not want to hurt her or be wasting my time hoping there can be a reconciliation.
What should I do?
