Input: During this winter, a friend of mine and I talked about how we both love playing volleyball and we should go play when it gets warmer on several occasions.

Last week, I saw her playing with other people from school on her Ig story, she actually had called me that day to see me at school but I was already at home, so she knew I was free.
She casually mentioned this event afterwards, saying this is the 2nd time she played with them and intending to do so again. I somehow got the sense that she only mentions this bc I already saw it on Ig and there is no way of hiding. These are the people I know of so she could have invited me with no problem. 

I got upset but figured no one ows me anything and this person showed me she is a good friend on different occasions before so I will let it go. 
But natually, I can't act the same way I used to with her. Last week I didn't see her at all, it's not diffucult to avoid since our schedules are different and when I see her I can't help but feel cold to her and she realizes something is off. AITA for feeling and behaving this way?
