Any advice on how to flirt with women with low self esteem (whether or not you yourself find them highly attractive). They seem not to believe you when you call them beautiful thus they get strangly turned off. Also, I called a woman “girl” and she corrected me quickly in an attitudish way saying “I’m a woman not a girl”, even though I apologized she still seemed turned off. Any advice?

EDIT: Just to be clear, I wasn’t aiming for the looks when we were talking. I just called her Beautiful that’s it. And also, someone in the section mentioned comfort. What are ways you can build comfort before getting her number because if she is not comfortable in the initial interaction, how will you get her number?
