Hey, I wanted your opionion on this situation. Ill try to make it quick and simple.

Last friday I was at a nightclub with a bunch of friends. A group of people were at the table at our right and they turned out to be old friends from elementary school (I just finished college). I go to say hi to a female friend. I talk to her for a bit and then, she tells her friends: Hey! do you remember this guy? (Me, 23M) One of her friends 23F, HB8.5 waves at me to go say hello. It was 3.am and I was kind of drunk so I didnt go. After a couple of minutes she waved again and I went to say hi. She was very excited to see me, she huged me and we talked for about 1-4 mintues. Then she told me: Hey add me on facebook. I wrote my number on her phone and told her: Msg, I dont have battery. She texted Hellooo at 3.15 am. He said: this is my boyfriend (LTR) and told him that I was her childhood friend (we were not close). He gave me a shot and while I kept talking to her she was rubbing my back and arms in front of this guy. I left afterwards and at the parking lot I met her again, she screamed my name in front of her bf and we talked for another minute. On monday, I texted her she answered quickly and with alot of ! and hahas. I told her I enyojed seeing her and she said she did tooo. On tuesday I texted her again, answered within 15mins, and told her: Guess what I remembered? She said what?? Me: You used to make drawings of my name and paste them on my pencil case. (her elementary boyfriend would get really jealous) Her: yeah... and on wendsay I texted her again. Told her: it would be cool to see eachother, let me know if you guys from school get together or we could arrange someting. She answered: Yeeees 100%, I will let you know. I thought she was hitting on me and believed there were IOIs. I really didnt know what to expect from the situation. Whats your take on this?
