I hate to jump to conclusions here. And not wanting to stress you out. But if this is a new behaviour, and she hasn't in the past over reacted with such intenstity to things..
I would be wondering if her reaction is trying to tell you something.
I really really hope I'm wrong on this one.
But please be aware that the behaviour she is exhibiting can be a sign of abuse.
Reassure her that you both love her too. She is feeling insecure and is developing understandings about relationships. She needs to be supported and shown that your love for her is unconditional and you won’t not love her just because you are showing love to someone else. Some children will need more reassurance than others. Talk to her about what she is feeling when she gets angry. Hope this helps.
We have the same issue with my step daughter. She will stare and and get angry and run off to her room and slam the door. 🤷🏻♀️ Been together 8 years. She’s always been like this. I don’t really know what to do so no advice. Sorry!
