22 years old student here.

Quick story coz I already think this kind of shit got posted here but I can't find it so I'm gonna ask again,..

A girl I like from my squad of friends likes me too, but when we made it clear to each other and the whole group now knows that we are into each other she has suddenly changed : from wanting me in all the squad meetings and not being able to laugh without my existence to not giving a fuck about me and actually preferring to spend time with them even when I ask her to go hang out alone.

Can someone explain wtf just happened?
