Yesterday, I (19M) was at the club with my friends and they left pretty early. A girl (19F) sent a Snap from the same club so I asked her if I could come at her table (I knew her from before) because I didn't feel like going home and I also wanted to try to get laid. She said sure, and when I got there she was really flirtatious and it was all going pretty smooth. Then, after like half an hour, she suggested we go to the bar (bar as in the counter, not as in the American word for pub) and get some shots, so we did (I paid obviously). Then I offered to buy her a drink, which she declined, so I wanted to buy myself a drink but she told me "Don't. Let's go." At first I thought we were going back to the table, but she started heading in the other direction, towards the exit. At this moment I was preparing for the best, I thought that she's leading me outside and that we'll do the thing. However, when we came to the point where the path for exit and path for toilet intersect, she stopped, said she's going to use the toilet, and told me to go back to the table. Now that was very confusing to me, I didn't get why she led me there and told me she's going to the toilet instead of telling me straight away when we left the bar. When she came back, she wasn't flirtatious at all anymore and I honestly felt like an outcast at the table (I forgot to mention that there were also her two female friends at the table). She wasn't paying any attention to me, only to her friends, so I soon said I got to go and left. Do you think that she initially wanted to go outside the club but abruptly changed her mind for some reason and used the toilet as an excuse? That's the only explaination that makes sense to me, because why else would she say "Let's go", lead me towards the exit and then tell me that she's just going to the toilet and to go back. The change of behaviour when she came back also suggests that.
