Well, my parent's are divorced, now my mom want's to go to another country. I want to remain here (I can go to my dad) but I want to live with my mom. What do?
You have to go with what you believe would have the best outcome on your life. What country does your Mom plan on moving to?
I think you should with the person that you feel most comfortable with. I mean someone you can express your feelings to and someone that will truly support you.
If it's truly your choice, I would say it's much harder to change communities entirely.
Most of the time in divorces the parents will end up making the decision for you.
Try to persuade her to stay. That may work. Or just move with her. It will be a fun adventure.
Let her know that you do not feel comfortable leaving home.
Go to the one who can give you a better future. Or, persuade your mom that this is the place for you. Insist on it and prove it to her.
