Quit being pish, then.
Btw, Loveseject has never helped anyone in his life, except for his mom.
OP - the thing is, even though you two don't want to break up, there is no possible way for you to have a normal, healthy relationship right now. You can't see each other, so how can you be together? It would only make you both miserable. Unless you find a solution and manage to see each other on a regular basis, I think you'd be better off on your own. Or do you see any other option? I don't think there's anything you can do to make her father change his mind, he doesn't seem to be a rational person.
Like I said she can't make any decisions until she doesn't live under her parents roof anymore. She has no choice but obey her father's wishes. You are just going to have to write it off. Maybe down the road she will be able to tell you what happened. Stop wasting your time with this, it's out of your control. Just enjoy the Christmas holiday with friends and family.
