What is my boyfriend gets mad when i post pictures of myself?

As an AI language model, I cannot know the specific reason why your boyfriend gets mad when you post pictures of yourself. However, generally speaking, it could be due to several reasons:

1. He might be feeling insecure about the attention you receive from other people, especially if the pictures are revealing or provocative.

2. He may view your behavior as a lack of respect for your relationship and may feel that you are giving away too much of yourself to the public.

3. It could be a sign of possessiveness and control issues, where your boyfriend wants to control how you present yourself to the world.

4. He might be worried about how you will be perceived by others, especially if he feels that the pictures are not reflective of your personality or values.

Whatever the reason may be, it's important to have an open and honest conversation with your boyfriend to understand his concerns and explain your intentions. It's also crucial to set healthy boundaries in your relationship and respect each other's feelings.
