Hi, first sorry my English, i am Brazilian

It has been a while that I am losing my frame when my 3 years LTR disrespects me. Some times she speaks louder or talk in a rude way, and this make me freak out, because since the begining of relationship I always said to her that I will not tolerate this. She understood, but sometimes she insists in do this.

My answer to this always was break rapport, stop texting her back or answer the phone when she call

But now I'm not able to keep frame and be patient with this behavior, and yesterday i loud and insult her, because she was speaking louder near her parents. All this resulted in a big arguing and a shitty new years Eve

So, I need an advice about what should I do when my LTR disrespects me, like speaking louder or being rude. Also, what can i do to control my anger. ? I already lift, but seems not working to this

Thanks.
