<human>: Everything was going great with my gf except she has some issues when she gets drunk, she turns into a raging angry temper machine and i've always been aware of it.

Basically we went on holidays for a weekend with a group of her friends and their bf's and she got really drunk.

I declined having sex with her because her friend was passed out next to us and she started kicking and punching and screaming punching walls and then punching her friend and her sister came and picked her up to take her home (i was too intoxicated)

The next day she messaged me saying 'im sorry about last night and i think we shouldnt talk anymore' We havent spoken since and she refuses to reply to me.

How could things have gone from great to absolutely shit in a night, without me even doing anything wrong.
Opinions are appreciated thanks :)

Could you distill the essence of the text into 1-3 sentences?
