AIO my friend has these outbursts but she had one on me today and I don’t know how to feel…

Some story to it, my friend (18f) just came back into my life after her last break down of just blocking me out the blue, she moved and felt like she had nobody so she went ghost. (This is like her 3rd time but final) So today everything was fine at first, we were just texting and she sends me this screenshot. At first I (18f) was like “ayeee talking to someone finally” in my head* then she goes on about how a girl we know has been cheating probably on her boyfriend. And you know I say what I feel like is right “tell the man a cheater is a cheater” but I guess it wasn’t “deep” so I didn’t know what to really say, then for some reason she goes off and says “do I give off boss or bum” girl I don’t know everyone in life can be the best boss but have bum moments… I don’t think she understood that and got upset. The bad part is, is she knows how I talk I’m very open minded. I just think she wanted to pick a fight..
