If a girl tells you that she dreamed about you, is that a hint? Should I confess again?

From your explanation, I can basically see that you are a more responsible man. You probably think that material security is the foundation of love. Then I will give you a neutral opinion. If you really like her and want to keep your promise, then you should explain your true feelings to her clearly, and then give a compromise: for example, I can always love you until you are 25 years old, but you have the right to be loved or loved. If you can still be happy after the age of 25, we can always be good friends, if you haven't found true love.
