How to cope with your family breaking up in front of you?

Remember that this is your parents business. There really is nothing that you can do. I am uming that they have grown apart due to the distance and that perhaps your Dad has a new lover. You cannot get in the middle of these kinds of fights. So my best advice is to leave, get away, keep your distance, and make plans for your own future. Dream of how you would like your life to be in 10 years, and then go after how to make it happen. Your parents might be a huge part of the life today, but once we grow up, our parents dont play such a huge role in our lives as when we were children.
