What does it mean if she tells her mates of me ?

You are asking the wrong question. You need to develop the ability to read body language and facial expressions if you are going to be able to judge whether or not she is interested in you. Which is what I think you really want to know. When she looks at you the way she does what does your heart say to you about how she is feeling toward you. If you don't know then start paying attention in other types of situations and start listening to your body and to your inner wiser self. That intuitive part of your mind that speaks to you to tell you what is really going on. It speaks in a quiet matter of fact way in as few words as possible. For instance in a dangerous situation it says "get out of here". In relationships it says "she is interested in you". There will be that look in her eye. The fact that her eye contact is just a tad longer than the usual eye contact. There may be a slight smile on her lips. Pay attention to those small details. Smile at her and see if she smiles back. Develop a style of flirting and see if she responds positively to you. Try to speak to her even if it is just to say "hello" opening the way to eventually being able to say more to her. Don't worry about what she says to her friends. Good luck.
