terrified.. in A Day in the Life of Me

We have nothing done paperwork wise.... nothing. I am terrified that he is going to end up going home, and then it will be another 6 year battle to get him back here.... I don't know what to do.... I kinda quit harping at him over paperwork cause it wasn't getting through, and now a month away from his visa expiring and the wedding and now, im in freak out/panic mode... /sigh.
