She thinks the amount is too small. If your's relationship has been very ambiguous, and she has almost become boyfriend and girlfriend, and the amount of red envelopes you give to girls is relatively small, such as 5.20, 1.88, 13. 14, then girls may feel that you are reluctant to give her money, and she will think that the amount of red envelopes given by boys represents her position in your heart. Therefore, the amount of these red envelopes you sent is obviously unacceptable to girls. If you receive them, you may get them all back. Therefore, when sending a WeChat red envelope to a girl, it should be based on the intimacy of your relationship.
She believes that the relationship between your should not be proved by money. In real life, there is such a girl. She felt that your was related to a certain extent, and there was no need to prove anything in the form of a red envelope. She is very confident, even sure, about the relationship with your. Therefore, she won't accept your red envelope, and may come to explain the reason to you, so that you don't think too much.
4. Girls reject you indirectly. Some girls think that you are not suitable, but if you are explicitly rejected, you will not be able to use your WeChat, not accept your WeChat red envelope, and give you a cold shoulder. So, if a girl doesn't accept a WeChat red envelope, it may mean that she rejected you and you can give up.
The girl was busy and didn't see it. If the girl had a good chat with you before, but suddenly she didn't reply to your message and didn't accept the WeChat red envelope you sent, it's likely that she was busy or doing something else and didn't see your WeChat message and WeChat red envelope. In this case, you can wait and see, and the girl will reply to you when she opens her mobile phone.
