Why are you so keen specifically on a Brazilian woman? I suggest taking it easy for a while, and focussing on meeting people in your immediate vicinity.

How I do smooth things over because I really want to be tiptoeing around every social event I potentially go to nor do I want to make a scene and humiliate her either.
Less "standard", more "rude and unclear".
I suggest apologising for your bad manners, and explain to her that you felt your arrangement has run its course (no "I'm sorry, but", no excuses. Just "I'm sorry. I should have talked to you. I was wrong. Here is the situation.").
