If doing the right thing means losing your family is it worth it?

Im married with a child and have been unemployed for a year. Right now we have a sweet deal going with her folks were i go to school get my AS and we move out but the problem is were in such a bad financial spot that im not able to go back to school even with G.I. Bill and FASFA support. My brother has offered for me to move near him since there is a great job market by him, but, my wife REFUSES to move. She doesn't mind if I leave for work but she wont budge. Im afraid of prior relationship issues magnifying when I leave and deep down I know I will lose her when im gone... And it absolutely kills me to even think that. Im trying to do everything in my power to take care of my family and do the right thing but dammit when is doing the right thing actually doing the right thing.
