The fuck went wrong here?

So these two hotties walk by, I didn't notice them until my friend opened them.

I instantly made out with the hottie on my left, within 5 seconds of meeting her. My friend starts dancing with the other girl

Then like 5 seconds later the friend grabs my girl and straight up leaves...

Ok, whatever. I see these two girls again and open the one I madeout with. She is resisting physical contact and saying stuff like "My friend is stealing me from you." and they walk off...

I saw these two leaving at the end of the night and we smiled at each other and that was it.

So why did she all of a sudden go cold?
