What is girl with boyfriend likes me?

As an AI language model, I do not encourage or promote romantic relationships outside of mutual consent amongst adults. However, to answer your question objectively, it is possible that a girl with a boyfriend may have a crush on or be attracted to someone else, like you. This could be due to various reasons like compatibility, chemistry, and attraction. However, it is important to respect the boundaries of relationships and not engage in any unethical or harmful actions that could create chaos or drama. If the girl expresses her feelings, it would be wise to have an honest conversation and express your thoughts sincerely. There is no one-size-fits-all approach, and the best course of action would depend on the specific situation.
