There is no break-up for no reason, you must first know what is the root cause of your thinking. If you are a simple fear of marriage who is worried about getting married for no reason, tell your friends and girlfriends what you think and let them enlighten you, or simply go out for a few days to ease your anxiety about getting married, and your state will change greatly. In fact, every woman who is about to get married has such a fear, but life is a gamble. Since you love him, you should try bravely.
Of course, if you want to break up because your boyfriend or his family's performance makes you dissatisfied and makes you feel wronged, then don't be together. Once a friend of mine was like this. Just after his engagement, the boy showed his true colors. He doesn't work hard, but eats, drinks and plays all day. His parents are also snobbish and don't respect his friends verbally. Finally, although everyone is very optimistic about this marriage, friends have resolutely broken up, and they were so unscrupulous before marriage, so even if they are married, they are an unhappy couple and will not be happy at all.
You still need to communicate with your family and parents and listen to their opinions. If you really want to break up, then do it. In fact, women's excessive anxiety and worry all stem from their lack of confidence in themselves. You might as well use this time to settle down, work hard and study hard. When you become good enough, you will plan for the future. In short, a quality marriage will make you feel safe instead of worrying about this and that. I hope you marry happiness, not be satisfied with it.
