There is this hot girl, who used to be my classmate for 5 years (this was 3 years ago). We became good friends in school even though we never call,write each other or plan a meeting. It is always just a random meeting.
Yesterday they joined our table in the pub (there was 7 of us at the table) and we were sitting next to each other, so we could have a good talk. She was always smiling and laughing with me, and there were also lots of touches. I thouched her alot (arm,thigh) and so did she. She invited me on her birthday next week so I guess I am comming with my friends.
If I wouldnt know her for that long, I would 100%ly know that she is so interested in me. But in this situation I am kind of scared, because what if she will be so shocked and tell all her friends what an idiot am I?

.. Is there any safe way doing this?? If you guys have experience with something like this please tell me what you did..
I appreciate any kind of help.. thanks:)
