1) Reduce alcohol intake
2) Game other girls in her vicinity, get them having a good time with you/all over you, then hopefully she'll get a little jealous that she could've been the one having such an awesome time with you. There's your in. After gaming these other girls, just casually strike up a conversation with her, not trying to get anywhere or anything, be detached and open to leaving the conversation at any time for a better one, make her work for your attention and I think that'll get her putty in your hands
