we have joint custody of our 4year old daughter. atm i have her every other week.my exwife is unemployed,and just filed for chapter 7. the fact that she will lose the house makes me think that she will move to a different area (move in with her boyfriend). She also have a drinking problem and i think that she has been arrested for dui a few months ago. i am a perfectly fit father matching all the criteria while she does not at any point. Do i have a case?
