Strange flashback!

[Could_this_be]

Over two years ago... I met some chick at the bar. Later on that night we went to her house. I got really drunk and the next day I woke up next to her on her bed. I didn't know wether we hooked up or not. When I asked her -- she said no. One that same I tried to hook up with her in the morning and she wouldn't do it. Two months later... she lives really close to me so two months later I went to her house again, and she wouldn't hook up with me. I have never had unprotected sex before, and no matter how drunk I had been. I wouldn't do it -- even with a condom on I would be very cautious and nervous as far the condom coming off or anything that would put me at risk. Now that everyone put me at now risk here. I called this chick up this week and asked her about that first night, and if we hooked up or not. She is acting very strange as if something is wrong with her... and this is scaring the hell out of me. We text each other back and forth and she is telling me that she has got tested and she's clean and we didn't do anything that night. But she is very sensitive with her text messages. I told her that I have never put myself at risk outside that night -- in which I don't remember  what really happened. If she has something and we hooked up... would she hide this from me?
