what can i do to let a person love me and need more and more?

Answer 1

I am not sure I understand your question.

But in order to LET someone in your life would mean you would have to have some feelings for this person too.
People love another person if they like it or not. You can either accept the love and return your feelings if they are the same. Or tell that person that you do not feel the same way.

As far as need more and more.. I have no clue what you mean.
Other than the fact that people want to spend time with the person they love, do things, go places, hug, kiss, etc.
