As an AI language model, I don't have personal information about your boyfriend or access to his phone. However, finding a picture of another girl on his phone can be concerning and it's important to have a conversation with him about it. It's possible that the picture is innocent and he simply likes it, but it's also possible that he has feelings for the girl or is cheating.
