Everyone, we have our answer as to why she shut down. I don't fully remember this, but she has told me that I made some joke about girls who wear chokers and that they have daddy issues (she was wearing one). That night marked the one year anniversary that her father passed away. I am an enormous asshole. She has said that what I said is irredeemable.

I had no idea her dad had died, but of course I don't blame her for getting upset. Do I deserve a second chance? Probably, since I didn't know about her dad, but tonight she told me not to contact her again, so I won't. On to the next female.
Arch, I need to start doing this. The problem is that I feel lame if I stop drinking on like the 3rd drink. Any more than that I start getting drunk. Can't have a woman out drink me ya know? How do you play that off?

Yeah, keep an eye on that. I stay sober on dates/meet ups. Helps keep wit intact.

why do so many threads have guys saying they can walk away, but they never do?

It's an awkward joke in most contexts...like daddy issues aren't something I'd joke about with a new chick...it's just weird imo.
