I had the same issue Rosa had... is it the NEW opportunity that would take you away from the family more? If so, perhaps now isn't the best time.
Maybe the old JFun would have thought the money and the opportunity was a big priority. But I think the new JFun probably realizes that right now your sons needs you more than ever.
Looking back 5 years from now do you think your regret will be, "I wish I had taken that job and gotten the wage increase" or "I regret that I left my children more dependent on W, when she was not in a position to step up and handle it."
I don't know all the details, but I would say anything that makes it harder for you to be there for your sons through this is probably not the right call at this time.
