I dont think breaking up is the answer omnimax and I disagree with Wakeup.
You and she were moving, staying in hotels. I remember when me and my partner moved house it was so stressful and we argued a lot for a few days and we rarely ever argue normally.
I think if she understood the situation fully-she would be more supportive and you can try to talk your parents round. Tell them you love this girl, she didnt mean the things she said and is truly sorry. Surely they can put their negative feelings aside for your sake?
There was a similar situation in my family where my uncles wife caused war between everyone about a year ago. She was a nightmare and it went on for months but everyone got over it and we don't hold a grudge. Shit happens sometimes. People make mistakes.
