Let's get straight to the point. Most women are actually not that difficult to read. This is certainly the case when you know what to look for. Once you know those signals you can then observe more closely to make sure that she likes you.

The first proven way is this. If a girl pays attention to you she has some interest to begin with. This is especially so if she is in conversation with others and is now and then looking over at you. Have you ever done this when you are into a girl? There you are a at a restaurant talking with your friends but having some cute girl on your radar looking over there on occasions to see if you can maybe attract her attention. That is why it is a proven fact. People look at things they like.

The second proven way to tell if a girl is in to you is based upon how she acts while in your company. Any of us who are interested anything have far more engaging body language than when we are not interested. We get a little more animated. We sit up and pay attention. We engage in conversation and generally we seek to find out more. So if she is with you and is generally inquisitive regarding what interests you then she obviously likes you enough to want to find out more.

The third proven way you can tell if a girl likes you is by how she behaves when other women are around you. If a girl likes you she will generally let her female counter parts know that she has marked her territory. She may not necessarily do this consciously but based on her body language she will make it clear. She may even get jealous and get involved with your conversations with other women while moving close to you.
