What is he ignores me but talks to everyone else?

When someone ignores you but talks to everyone else, it could mean a variety of things. Here are some possible reasons:

1. They may not be interested in talking to you. This could be because they don't enjoy your company, they don't find you engaging, or they simply have more interesting people to talk to.

2. They may be shy or nervous around you. Some people find it easier to talk to others when they're in a group, but when they're one-on-one with someone they feel intimidated or anxious.

3. They may be upset with you for something you did or said. If you had an argument or disagreement with them recently, they may be avoiding you as a way to express their displeasure.

4. They may be dealing with personal issues that have nothing to do with you. Sometimes people struggle with anxiety, depression, or other mental health issues that can affect their behavior and interactions with others.

5. They may be simply busy or distracted. It's possible that they're so focused on other things happening around them that they're unintentionally ignoring you.

In any case, if you're feeling ignored, it's always a good idea to try to talk to the person directly and ask if there's something specific that's bothering them. This can help clear up any misunderstandings or issues that might be causing the behavior. However, if the person continues to ignore you or doesn't seem receptive to conversation, you may need to accept that they're just not interested in talking to you and try to find other people to connect with.
