A lot of twitter users were left in stitches when a chat between a girl and a boy were exposed. From the chat you can tell that there is no longer trust I the relationship and that is probably the reason why the guy reacted the way he did.
The girl in the conversation sent a picture of another woman and did not say anything. They guy kept quite then the woman decide to check if he had seen the picture then suddenly he became so defensive.
The woman calmed him down and told the man that she simply wanted her to see the hairstyle that the woman had. Maybe she probably wanted to do the same hairstyle and wanted the boyfriend’s approval. He was quick to think that he was being accused of seeing another woman.
