Friend trouble help!

Ok so my friends said that we'd all hang out the next day and that night I confirmed it and they agreed that yes we would hang out. So the next day comes around and I'm texting both of them about what time we should hang out and both of them didn't reply. So that night I texted one of them telling them my feeling were hurt and she apologized and the other one didn't. And we haven't hung out since. She hasn't texted me or anything and we were like best friends. Should I let her go because she doesn't care about me or should I confront and talk to her about it??? Help
