The girl I once liked sent me a text message: Sometimes life must do something, and there is no need to insist all the time. What do you mean? How should I reply to her?

Sometimes there must be something in life, and there is no need to force it in life. This sentence means that people's marriage is doomed. If they are destined to get married, they will come together sooner or later. If they are destined to be partners, then even if you try harder and spend more time on it, you will eventually draw water with nothing, which means that everything will go with the flow and don't force it.
