<human>: Me and my girl have been together for a year and a half but now for the last 5 months, we constantly fight every week because we do unhealthy choices, we buy pizzas, ice creams etc. and eat everything while watching a movie. And then she starts regretting everything we done that day and stats blaming us for not wanting to change or look fit because its her number one priority, to be a fit couple. 

Now I'd like to mention that we are no wear near being fat, but the thing is that we both go to gym for a bout a year but our bodys hardly changed and that's what makes her sad that we regress. I do love my girl, but this is getting out of control and now she put ultimatum if we have  another cheat day with out any progress, we both will be on seperate ways. This just makes me sad, we both decide to eat unhealthy on those days, but she's the one bringing it up later and now it got that much real that she puts our relathionship at stake. And now I don't know what to do, its absurd to me that somebody would like to end relathionship just because we have an eat out. Am I the one not understanding enough or she's the one  being psycho about it?

Can you summarize the given text in a few sentences?
<bot>: Gf mad that we both eat junkfood and dont show any improvement in our body. I don't care that much about appearance than she does and thats the reason she wants to break up.
