How does everyone hold up while your loved one is away? I don’t know how long he’ll be away for. . . but will most probably be years. Not sure where to turn when my family doesn’t like him and I recently got into a disagreement with his family. How often do you write because I’ve been writing everyday wondering if that’s to much. I have no idea how to handle all of this and I’m scared for how much time he will get. Help?
