Things we could all do?

My mom and dad after 22 years of marriage filed for divorce back in March. They both want to work things out but a location for them to live together is hard to figure out. My mother moved out of state to be with her family. She is coming up with in the next couple days to see us all and to get my two brothers to go down to where she is living for a while. My mom says she will not move back here because of my dads family. She doesnt want to be around them. The courts will rule that the boys stay here with my dad because of schooling. Her boys are her life. I do not understand why she wouldnt "suck it up" basically and just move back. 3 of her four kids are here, her husband is and my daughter (her granddaughter) is here, in this house. when she comes up we are going to try and talk her into moving back. Any ideas of things we can do for her to basically 'bribe' her. We all miss her soo much. We want her home!
