He certainly needs your care.

But what do you need from him?

Nothing is wrong that you have needs, you are only human. But if you think that he is going to care more for you by your caring more for him, you might be disappointed, in the future.

Express to him that you need his help, in words and deeds. Ask him to help when you do chores. Instill in him gratitude. Ask him to say "thank you" often. Point out to him the moments when he should express appreciation. Praise him when he is being thoughtful.

The goal is to condition a reflex in him a feeling of well-being after helping you out.

He needs room to develop into his own being. You should give him that room by stepping back and not smothering his breathing space. But this is not contradictory with your wish that he grows up a kind and caring person.
