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

Today, I broke up with my girlfriend after she freaked out while drunk on Thursday night. We have had very minor and pointless arguments in the past but this time round she really went for it.

I have experienced partners like this (both sober and drunken) in the past and I previously promised myself that I would never go through it again.

The last two years with her have been mostly great but after the freak out on Thursday, I remembered my promise and stood by it. I gave myself all of Friday to think this through and I was certain that breaking up with her was the right thing to do.

However, after today I feel horrible. She was super upset and apologetic and it made me feel very heartless.

Am I selfish for only wanting to be in a relationship that is free of pointless arguments? Do they even exist? Should I give her another chance even though she has no control when drunk?

Have any of you been in a similar situation?
<bot>: My girlfriend went crazy while drunk on Thursday night and today I broke up with her. She is great when sober but horrible when drunk and I now have mixed emotions over the decision I made.
