What is he stopped texting me good morning?

As an AI language model, I do not have any specific information about why someone may have stopped texting "good morning". However, some common reasons why someone might stop sending good morning messages are:

1. They may be busy or preoccupied with other things in their life, and doesn't find it important to send good morning messages anymore.

2. They may feel like the relationship or communication has reached a stage where sending good morning texts doesn't feel necessary or natural.

3. They might feel like their partner or friend doesn't appreciate or respond positively to these texts, and have stopped sending them as a result.

4. They might have lost interest in the person they are texting and stopped making the effort to send good morning messages.

5. In some cases, the reason why someone has stopped texting good morning might be deeper and could be a sign of underlying issues in the relationship or communication.
