If you're thirteen آپ have no say in whether یا not your parents want to move...if آپ really want to keep your girlfriend make it long distance, if not break it off.
this sounds a lot like the situation i was in. my dad was making us اقدام across the country and my girlfriend begged me to stay. i tried convincing him to stay but it was no use. we kept a 6 ماہ long-distance relationship, but then she broke up with me because it was getting too complicatd. i came back to visit, but when i left she broke up with me again. if آپ really love her, keep a long distance relationship. until آپ can اقدام back and see her again.
