There was a girl I worked with who would always flirt with me at work. After she found a new job and quit I got her number on her last day. I've been real busy the last couple of weeks and haven't had a chance to call her. I saw her last week at a happy hour and I started talking to her. Then mid conversation she went over to some of her friends and started talking to them. We hardly talked the rest of the night. Should I still call her?
