He needs you in his life. Your mere presence as a part of his life is enough for him. That is the language he speaks. You may not be able to create a "need" in him for other expressions of love. However, that doesn't mean he can't learn to accept your expressions of love.
Have you tried taking complete ownership of the need? By that I mean you present it to him as something that YOU need rather than something you think he ought to need from you. Acknowledge that your mere presence is enough for him, but let him know that you need to give him more tangible expressions of love. Make letting you be nice to him be something he does FOR YOU. I think this is probably what you mean when you say
Quote: I have even told him that sometimes loving also mean let other people love you,
But you might need to make it more explicit that you don't need him to need you to do these things. You need him to let you express your love.
