<human>: Can you give me the gist of the text in a nutshell?

Reading in r/relationships, I realized that I may be in a toxic relationship, lately fighting very often, well, during fights I am the one who do not yell at all, that is something my gf really hates.. because she lose control in every situation, she says "I act like teacher" because of the way I discuss. During fights is very violent with words, saying awful things non related to the subject, and has already hit me to 2 times, first time 2 years ago, and the last time 5 months ago. 

We are from different countries, we met in mine, spend the first 2 years living there together. The fights weren't often, I would say like a normal couple, then we moved to her country. And there is where the trouble started, fighting for anything.. normally because she doesn't like something or something is not "right".. But usually those things are not important staff.. (For example, I bought the wrong flavor of yougurt at supermarket.. omg.. she made a really big deal about it) And lately I can't stand the situation.. I am the kind of peaceful guy, I don't like troubles. Sometimes I am afraid that I do something wrong and then again into the toxic circle.. 

Well, when I came here (her country) I bought a 2-ways ticket (different continents, kind of expensive, and not much difference to one way) in case of anything.. perhaps things doesn't go well, I don't find a job , etc.. And the flight to coming back is in a week.. And I'm thinking about coming back, even thought everything besides the fights is perfect. I don't know if is the right thing to do.. what do you think?
<bot>: moved to her country, we fights lately very often, I think we are in a toxic circle, I have a ticket to go back to my country in a week, should I go back?
