how do guys know if a girl really likes them or is just friendly?

When a girl is really interested in a guy it is usually not at all hard to detect. She will smile when she sees him. She will hang around him longer than she would if she didn't really care. She eludes a warm feeling toward him but you need to be able to see it. Now if you find it difficult to say anything to her then you may have a real problem because usually that means you are focused more on how you feel than on what she is doing and you may never even see those signals. Trust me I know this because that is just how I am. It took me many years to get over that and to begin to pay attention to what she was doing. Pay attention when you meet someone. In general do they seem very interested in you or do they just go through the normal, nice to meet you, motions? There is a big difference and when you see it you will know it.

These thing can be identified by the eyes and smile of girls. Otherwise her body language depicts all thes things.Like moment of his finger and eyes

I think we can see in the eyes.Eyes are window of the soul and the enlarged pupil will show her love.But we can't move that close to watch her eyes.LOL!Still,we can learn through her body language and her voice too.There will be a special tone.You need a lot of observation to distinguish.Cheers!

This is a very complex issue.When a girl loves a person,the tone talked to him probably will be different with to others.

Lively and cheerful character of young woman often cause this tuouble. Dont worry about it. If the situation appears, you should tell him the truth directly and further away from him.
