AIO my gf is mad that i brought up the idea of sending my ex condolences bc her brother passed.

(i can’t add any more images of the texts i’ll make a separate post, bc it gets worse)

my ex of 2 years brother just passed, and i was close to him tbh. i was wondering if i should just reach out to send my condolences as it's only respectful right? my gf(20) responded this way though… also it was my bday and i was pretty much ignored for the remainder of the day up until when she started texting me at 2am…i just think this is turning out to be a big deal than it should have been and im at a loss for what i even did wrong in this situation. last night after the “argument”? she removed all her pics with me off all her socials and turned off her location. i just don’t know what to do i maybe need a new perspective to see if i genuinely did anything crazy and bad or wth happened.
