What should I do when a girl says she really likes me I make her feel good but she doesnt want a boyfriend now?

We have great conversations till about 1-2 in the morning, we text all day and she says she has never had someone be so interested in her happiness like I have been, she feel really good when I talk to her, she has told me that she really likes me but she also says that she is not ready for a relationship, I have explained to her that im not playin any kiddie games and that my intensions are good that I know what i want and that is to make her happy, what else should I do...
