For I have no man so of the same mind, who with sincere affection is solicitous for you.
For I have no man likeminded, who will naturally care for your state.
For I have no one like him [no one of so kindred a spirit] who will be so genuinely interested in your welfare and devoted to your interests.
For I have no man likeminded, who will care truly for your state.
I have no one like him. He is a person who genuinely cares about your well-being.
For I have no one else with such an agreeable mind, who, with sincere affection, is solicitous for you.
