My wife took a new job in another state last Mach, 2009 (West Chester, PA) and lives there full time while I am at our other residence (Massachusetts) until our son graduates high school (next year, he is a jr. this year). When he graduates, my sin and I will be moving to where my wife is now. We pay rent on these 2 different locations right now and need advice on how to file this?? Her job was a necessity, as there was no work (what she does) here in Massachusetts. Can we get some guidance?
