I sent my girlfriend a breakup message and she didn't call me back. Is this the default?

In fact, your friend didn't reply to you. At this time, he may be thinking that he may be disappointed. Why did he acquiesce in the reason why you broke up? I think it is inconvenient for two people to be together, so you must cherish each other's feelings. Your girlfriend didn't have any beautiful women and didn't say anything. If she is angry, she will reply to you immediately. He must be a little disappointed, or disappointed in you. Why do you say such a thing as breaking up? So I don't care what the reason is, if it is true, it is also difficult to get along with. It is really immature to separate because of a little thing. So I still say that, I hope you cherish each other's feelings and don't regret it in the future.
