I end up going out with about 3 afcs and a bunch of pretty hot french chicks who don't speak much english. We all go dancing most people leave at like 2am and its me, one afc and three chicks,i can tell one isn't interested, one I don't fancy and one who is just shy, so I concentrate on the shy one.

I have her dancing then things get pretty hot she starts grinding my leg and just generally looking horny! So as she doesn't speak much english I slowly work my way into a kiss and we make out for a couple of minutes on the dancefloor like three times. Then out of no where she goes "i have to go dance with my friends"she said it like an excuse to get away from me, but she had just been making out with me hard! so I'm like ok... She does for a bit then she just goes off and says she's leaving, all three girls disappear then come back! And they are normal except the shy girl I kissed who completely ignores me the rest of the night and on the way home.

She didn't seem angry, more like scared, she was only 18 I'm 23 but I don't know what I did everything just went crazy and bad fast, anyone got any thoughts on this? the thing that really confused me is how she seemed scared, I made good friends with all her friends we were all dancing

I think it's because she lost the interest in you.
you must use some push & pull...

hope that helps.
cheers

Don't listen to zenki... I think what happened is that she felt she went too far. If she is indeed shy, then making out for her was a big deal and she was confused about it. Anyway I would say just build some attraction to her if you are meeting her again and it will work out next time.
