When a girl is into you, you don't have to think much about how to date her, things will just naturally come through as long as you take the initiative and don't act too autistic. When she is NOT into you, no matter what you do nothing will work out, you could look into a thousand seduction tutorials and she will still reject you. Also don't be too clingy or it will turn her off real fast, speaking from experience （ ´,_ゝ`）
