I Need Some Relationship Advice?

I'm having troubles with a girl i like, and i know at least until last night she liked me to. Lets start from the beginning. She moved down my senior year of school, and we started to hang out. After a few days we became interested in one another, but she was kind of a drifter back then and scared of the new school and we ended up not dating. About three months later she started dating one of my friends and a year later they broke up. during that course i went through some hard times where i was a pretty bad person and we hated one another because we had different views a while later i cleaned up and she moved back to where she came from and got engaged after about a year and a half her fiance broke it off with her and she started dateing again one guy she dated she still cares for alot honestly i think she still loves him but she knows it wont work and therefor she moved back here and is going to school she rarely talks to the guy anymore but she cares for him so its understood here comes the bomb shell so the past 2 nights we have went to concerts together and afterwords going home and getting hammered the first night i took care of her because she was extremely drunk and i was still able to process and walk so i got her to my bed and told her to sleep there id take the floor she asked me y and i said so she could have it she then asked me to climb in bed and cuddle with her while we were cuddling we talked and i was drunk enough that i slipped and told her i liked her was interested in being with her if the opportunity ever arose she said she knew i liked her that she wasn't stupid and she felt the same then we passed out in each others arms the next day we got up and went to the concert she was driving and was didn't know how to get there so i tried to give her directions but on of my friends kept interrupting and me and him got into it she got pissed at that but about 15 minutes later she was ok with both us and we continued flirting having fun we went to the concert and i got shitfaced there and we went home and my smart *** drank some more with them this part i dont remember at all but from what she has told me il fill in what i can this morning i apologized cuz i wasn't sure what i had done but knew i could possible been an asshole she told me i was that she would rather not explain everything but she did she told me that i had cried on her shoulder for an hour or so about my past what i had done because in truth i feel really guilty i hurt alot of people in alot of ways then once i stopped crying i wanted a cigarette she gave me one and hide the pack after i smoked i wanted another and looked through the house finely finding them when i did she ran from me with the pack and feel on my bed telling me to go away i did and then she got up and headed downstairs i said could i have my smokes and she through them at me and walked down the stairs leaving me alone upstairs cuz she had had enough yelling she says the crying didn't bother her but me keeping everyone up till 3 and her having to yell at me so much had my biggest question is do you think i lost her interest i know noone can know for sure but id like to know what you think and also where do i go from here and once again i know noone can answer that but advice would be nice i would like to date her but idk what to do after she told me about last night she left to head back to her house because she has a wedding to be at i appoligize for the grammer but if u manage to read this plz respond
