<human>: So, I was supposed to go on vacation with my girlfriend's family and some other families for a week before she goes to university. She had to uninvite me because there was a limit on the number of people who could go on the trip, and they didn't check it until a week before we were supposed to leave. It might be worth noting that while my girlfriend apologized, the people who planned the trip didn't. 

I was kind of annoyed, but my girlfriend said that if I wasn't going, she wasn't going to go either, so we could still spend time together. I was happy with this. However, as soon as she told her mother this, all hell broke loose. 5 or 6 days of screaming, calling my girlfriend a terrible child, saying that she didn't care about her parents and all sorts of other stuff. 

My girlfriend has a bad relationship with her parents, and they are pretty abusive. Her dad used to beat her and her mom is very emotionally abusive, but irregular about it. 

Anyway, the day before they are supposed to leave, my girlfriend tells me that she thinks she should go  because it might make her relationship with her mom better (her dad decided not to go at this point), and her mom was really upset because she had wanted to go on this trip for a while. I said that I can't stop her from going, but I would be upset if she went because it felt like she was giving into her mothers abuse, and we would lose the time she said we would be spending together.

Give me the gist of the text in a nutshell
<bot>: My girlfriend uninvited me on vacation, said we would spend the time together, then left without me to try to improve her relationship with her mom.
