<human>: Can you give me a shortened version of the text?

A few nights ago I went out while my girlfriend was working, and saw two old friends at a restaurant.  It was me, a girl I've known since kindergarten, her little sister, and my little sister.  I told my girlfriend beforehand and she said "Oh great!  It'll be fun to see them!"

Later, she started replying to my texts all passive-aggressively with many "K"s and the like.  I asked her what was wrong and she told me to leave her alone.  

I called her, and she accused me of going on a date.  She then proceeded to accuse me of being in love with my sister.  I yelled at her then, the first time ever, and told her that was completely ridiculous.  

She said "At least I didn't go on a date with three other boys late night" and hung up on me.  We talked today and she apologized profusely, saying she said these things without thinking.  

We decided to take a 3-day break.  Should I simply end it?  

I have trouble with that.  She has loved me so well, and I am WAY too empathetic towards her feelings.  I find it very hard to simply end it and give up, even though there have been way too many fights lately, and the suggestion of breaking up has come up four times.  

Is it worth it?
