She is a teenager, she was in love before 2 times,
and her previous boyfriend really hurt her.
I accidently said a word by mistake and that word reminds her of her previous boyfriend and suddenly she gets rage and mad at me, she refused to talk to me.
what i said is normal, not at any way Insulting or offensive word.
I think i went through the same thing
There's this girl I was with for 6 months total
apparently after that, whenever I brought up something about us, she wouldn't talk to me at all. or just walk away or not reply online. They'd be simple shit that even ex's could talk about. but apparently, she didn't want to think about it, even though she said she didn't have feelings for me.
now, 2 boyfriends later... a simple word that reminded her about her recent boyfriend, really got to her.
I say, be patient, but not too patient. If nothing happens in less than 20 hours of silence or small conversation, then thats when you should be worried and start to be worried, and let her know how you feel, and how YOU would like her to feel. currently, and the future
leave past stuff behind, and be careful on what you say to make sure it doesn't remind of her ex boyfriend
