Things were great now she stopped talking to me?

so i got set up on a blind date with this girl who was best friends with a "girl" friend of mine. The first date was not so good cause we went to a movie and didn't get to talk much at all but i was very interested. The second date was for a friends bday dinner and that also didnt go to well but i did get her number and asked her out on this semi formal function my fraternity was having. She was very short with her texts and i didn't think she was into me but she finally agreed to come which was great. We had a great time at semi and we talked a lot. we both got very drunk and came back to my place. We started to fool around and things were getting pretty heavy and i stopped us cause i wanted her to think i was in this for the right reasons which i am. she even told me she liked me that night but of course she was very very hammered. she was still very short when texted but we went out again a few days later to lunch and had a great time. talked the whole time. then i stopped by a party of a mutual friend to see her and she was dead sober, i was drunk so i didnt want to talk to her that much so i would not sound dumb. I texted her the next day telling her it was good seeing her and that i was sorry i didnt get to talk to her much but i didn't want to sound dumb haha... and now she has not texted me back from that text in two days. what should i do?
