Controlling friend

I’ve had this controlling best friend since 2012. There’s too many stories to tell but we’ve always fallen out and gotten back right mainly because I’m such a forgiving and passive person. Honestly, if she’s not in my life it doesn’t affect me and I’m actually a little more at peace when we’re not talking. Earlier this week, I texted her about a situation I’m going through. I texted most people close to me the same thing once I found out the news just to update them right. So everyone else responded back like normal but with her all she said back was “Good Morning”. She does that because she requires you to have a greeting whenever you text her. I said I’m simply good morning back and that’s when she responded but it was very generic. I haven’t talked to her since.
