Hello. First time posting here.

So the story goes like this:

My classmate added my GF on snapchat and after a while they were talking not just like snapchating like you would with a stranger. I noticed that by accident when i asked my classmate what time is it and he was typing her a snap.

 After some time she said to me that he is cute. When i was at my GF's place she would in a way admire his snaps when he would send her one. At one time she opened his snap and she placed her phone on her heart and would go "ahhhh" in a way "he is so cute".

They never met before and at one point the passed next to each other and she texted me "OMG she just passed by me" 

Skipping to New Years party they would meet and hug and talk a little bit and they would split up becasue we were with my friend and he was with his. When to clock hit midnight 2019. Me and my GF would kiss hug and be together a few mins before she would say " im goin to congradulate him 2019" 

AITA for beeing mad by her admiring this guy and beeing happy about his presence near her?

Sorry for any grammar mistakes hope i wrote it good enough.
