What do you mean by sending a message to your lover and not returning it?

There may be many reasons for sending a message to your lover without replying. Here are some possible explanations:

1. Busy or distracted: Your lover may be busy with work, family or other things and can't reply to your message immediately. This doesn't necessarily mean that they don't care about you, but they can't be distracted for the time being.

2. Communication fatigue: If your lover often needs to process your information, they may feel communication fatigue. Sometimes people need some private time to relax, not necessarily because they don't care about you.

3. Technical problems: Sometimes, your lover may not receive your message in time, or there is a technical problem with their equipment, which makes it impossible to reply to your message.

4. Intentional alienation: If your lover stops replying to your messages, it may be a sign of intentional alienation. This may mean that they are not satisfied with your relationship or have decided to end it.

5. Lack of self-confidence or social skills: Some people may have some difficulties in communication. They may lack self-confidence or social skills, causing them not to reply to your messages.

Whatever the reason, if you feel confused or uneasy, you'd better talk to your lover directly. Express your feelings frankly and ask each other's opinions, so that you can better understand each other's needs and feelings.
