As long as you can do these two things, there will basically be no breakup.
Let's talk about the first one. What is to let her see the potential of you to let her see a happy life? That is, no matter whether your family is rich or poor, you can let her live the life she wants through yourself.
Xiao Ke thinks that she is willing to fall in love with you in college. She should be a woman who really loves you. She should also know your family situation, but she is still willing to be with you, which shows that she really wants to spend her life with you. But after all, it is college life, and there will be many problems in the real society.
Every girl wants to have a small family of her own and a man who loves her, so now you should try to give her a home of her own. No matter whether you have money or not, let her see that you are struggling and making progress, so as to give her a good life. Only a man who is not afraid of hardship and fatigue and is willing to make progress will let women see hope. If you don't work hard after graduation and your family conditions are not good, it's easy to lose women.
Many people say that girls are realistic and worship money as soon as they leave society. Is that really the case? It is not a girl's reality, but when she is willing to gamble all her life, this man is unwilling to fight for a good life for her. She can follow him for a while, but she can't be willing to follow him all her life. You can be poor now, but you have to work hard to get rid of poverty.
Also, you should always be kind to her as you are today, and let her feel that your love for her has not changed, so that she will have the confidence to follow you through her life.
