how do u know that a woman really like u?

Well..if the woman you are referring to knows how to express herself in a subtle way, you will know that she likes you when you see sparks in her eyes when she looks at you, gives extra effort in every little requests you ask, and listens well to anything you say. On the other hand, a woman may also show she likes you by simply appreciating any simple things you give her. As ethics would have it, we always say early to those that we don't like "lets stay friends" but if she doesn't tell it to you yet....you may consider it a good sign:)

I think you will know if the woman like you if she like to see you everyday, if she do things that really amaze you and do things that your not expecting her to do. like calling you everyday and asking you if your okey, like sooking for you or giving you something, or maybe when she is very angry with you with no valid reason.
