When your girlfriend asks you if you can support me in the future? How to answer?

You should tell her truthfully that you will try your best to bring a stable and happy life to your family, but in the current social situation, it is difficult for one person to shoulder the heavy responsibility of a family - for example, you still have to raise your own children. Older parents, they are getting older. Your girlfriend is a bit childish in asking this question. You can also ask her, I support you, who supports me?
