I am 23. My neighbor married women 30 looks at me. When I looks her, she plays with her hair, she makes eye contact with me frequently. But when I touch she avoids to make contact with me. She just looks at me. What do women really want,?

This is a married woman you're talking about. All women and men flirt to an extent but that's all it is. I suggest that you find a nice single girl for yourself and leave the married ones alone. It will only cause trouble. Especially if you're neighbors.
