Should I tell ATF why I’m mad?

Been seeing this girl ITC for over 3 months now

On three separate occasions, she’s brought up hanging OTC, and the flakes the next day. And, when I get with another girl, or she thinks I’m going to, she gets jealous, and sends cocky messages or asks me about it

This past weekend, she (for the third time) asked to hang OTC, I said yes. Next day she flakes, ghosts me mid-text convo, so I go to the club, and posted it on my IG story. She swipes up and says “Wow congrats you went without me😂”

I’ve ghosted her since Sunday. She keeps calling me, texting me, and today asked me why I’m mad at her.

Ive had an amazing time with her the last 3 months, but this shit is disrespectful. Do I tell her why I’m mad, or just continue to ghost her?

Have any of you dealt with a similar situation?
