My husband and I are living apart, but haven’t gone through a formal separation. I earn significantly more than him. If we divorce, can he claim financial support from me? And if I buy a new house, will it be considered shared property? Can he claim ownership of my existing assets like my shares?

Yes, your husband can claim financial support from you in a divorce, even if you’re living apart, based on your income disparity and the duration of your marriage. A new house purchased during the separation will be considered your separate property, but your existing assets, including shares acquired before or during the marriage, are potentially subject to division as marital property.
