What is we used to talk everyday now he ignores me?

As an AI language model, I don't have any specific information about your situation. However, if someone used to talk to you every day but is now ignoring you, it could be for a variety of reasons. Some possible reasons could include:

1. They are busy: The person might have a lot on their plate right now and don't have time to chat as frequently.

2. They are going through something: The person might be dealing with personal issues or problems that are taking up their time and energy.

3. They lost interest: Unfortunately, people's feelings can change over time, and they might not be as interested in maintaining the relationship.

4. They are upset with you: It's possible that the person is upset with something you said or did, but they haven't communicated it to you.

5. They are struggling with mental health: The person might be going through a tough time and needs to take a break from socializing.

In any case, it's always best to try and communicate with the person to figure out what's going on. If they are consistently ignoring you and not responding to your messages, it might be a sign that they need some space or that the relationship is no longer a priority for them.
