You were fine all the way up to the point where you started to bear a little of your soul to her. Quite simply don't do that anymore. You're so excited about possibly getting a girl that you're losing control of your senses. And if you're saying these things under influence guess what you're just going to have to cut back on the drinking then.
Making out on the bathroom floor is good, telling her that you like her was not. She obviously was looking for a fun, no strings attached, experience. You were adding strings to that deal by becoming attached and she didn't want that. Should just keep it fun and I bet that's exactly what she was thinking.
If you want things to escalate let fate take care of that. Just keep your game up, keep things fun, and if relationship happens to come out of it in the long run then go with it. Don't try to make it happen.
