I hit up a girl through Snapchat who I knew to be taken by commenting on her story. I went to In and Out and sent a picture captioned "what do you want?" And she said she lived close by and would come down. She arrived and we sat in my car and talked; sex, relationships, bs random shit. I didnt make any moves because she is taken, what do I do? What angle can I work to open the back door?

Edit: reason I didnt make a move is I was not expecting to see her so I wasnt really in a state to do so.
