<human>: Firstly let me say i'm hopelessly insecure, pathetic etc etc, this doesn't need to be pointed out to be.

I went out to a bar with a few close friends of mine, and they brought some girls that they knew - who i didn't. Anyway, everything was going good and there was this one girl in particular I really was enjoying talking to, we both had loads of mutual interests so we were literally just talking for hours and laughing , i really enjoyed just speaking to her.
anyway, at some point during the night the rest of the crew went off somewhere and it was me and her just sitting there at the seat thing just talking which was fine, but then some random guy from the bar came over, made small talk and banter which we both loved and then he asked us "are you two together?".

she then responded by laughing a bit and then saying no... this is where the night went downhill for me.

did she laugh because she was repulsed at the idea of being with me? was she laughing at the idea we could be ever date?
this really ruined things for me as i felt quite humiliated. i mean obviously she was going to say no because were not together, but i dont understand the laugh before it - it made me feel so small and ugly. anyway that guy went and the mood was ruined for me so i quickly left too.

the worst part was that I wasn't even thinking about her sexually etc when we were talking i just really enjoyed talking to HER, i mean she's beautiful which i noticed at first but i pretty much forgot how hot she was when we were talking she was like one of the lads. i wouldnt of mind having her as just a friend but the idea that shes disgusted at the fact we could be together just makes me sad.

am I overthinking this? what does the laugh mean? ah god im an idiot
thanks alot for reading anyway and i hope you all have a great day
