First of all, do not listen to anything your X says. You are right, she is thinking of herself first. Your boys need you in their life; I already know you would never consider that option!!!
If you do take the job, I don't think you have to make a long-term commitment; but work there until you do get a job that's closer to your dream job? I mean, it sounds like they are not offering a long-term job either. Could your boys maybe attend a private or Christian school in that area if all the schools are not good? If you could find a good school, then maybe you could move closer to the job so you wouldn't have to commute so much each day? I am going to add you to my prayers...
