This girl, who's been my sisters friend since 2cond grade came on to me at a party while drunk, saying she liked me for a very long time and how she thought I was sexy and wanted me and tried to have sex, but I declined because she wasn't sober enough. I ended up getting her number texting her but she never texts back. What's her deal? Why say you like somebody and want them and think there sexy, But when they try to talk to you, they ignore you. We are both in are 20s by the way. Why doesn't she text back? (fyi as far as I knew she was straight)

She may not even remember coming on to you. She may have thought the whole thing was a huge joke, or someone put her up to it. She may be so repressed that she can't handle it. Who knows, and why speculate? Leave it alone! Don't contact her again.

She was drunk and it obviously meant nothing to her.
Forget about it.
