**TL;DR WARNING** I would really appreciate an OP's perspective on my recent dating situation but really anyone's opinion is welcomed. First a little background.. We met on match.com, she winked at me and initiated conversation.. We emailed back and forth for about a week until setting up a 1st date. 1st date: Nothing too formal, had a couple of beers together at a local bar and played darts. There was definitely chemistry from the get go and pretty much throughout the whole night. I had plenty of opportunities to go in for the kiss but decided to restrain myself out of respect and to show her that I wasn't all about a quick lay. The night ended well and a 2nd date was set up for later in the week. 2nd date: We go out in dowtown Austin with her sister and her sis' friend. This time there is even more chemistry / flirting back and forth, so much so that it was palpable. A few drinks later we are both dancing and making out.. Now this is where it gets all fucked up, she goes to the restroom and comes back and is totally different. After asking her what was wrong, she said "she was really tired." So I asked her if she'd like to call it a night and head back she agreed. So I closed my tab and we left.. not much was said on the way home, but she held my hand like everything was cool. We had another makeout session when I dropped her off and everything seemed copacetic. Now here it is Monday afternoon and I haven't heard from her since that night. Now maybe I am just being paranoid but it seems like something happened to drastically change her feelings about me from sat night until now? Or is my intuition correct and I should just move on? Update: Just invited her to lunch and she declined.
