Dude.....the HB was definitely interested. You just had some logistical issues. on the train ride back I would have begun to escalate, simply because you are going to her house to get your stuff right? So she would have been all escalated up and you would have been in her house. bingo. But that being said, if you didn't escalate on the train ride, and made it boring, that kind of kills the attraction. I think because an opportunity wasn't taken by you she accepted other plans, and now has noticed the awkwardness and is a little confused herself on what to do next. I believe you could try to game her again, but personally I'd learn from this, find another target, and don't make the same mistakes again. I hope this helps.
