One year is almost never a spousal maintanence situation. And working only 2 days a week because as a hairstylist you couldn't find work closer to home would be ... well, laughed at... in a court of that locale. The judge will remember what a hard time his wife had in finding a decent stylist and how his neighbor, whose wife is a salon owner and can't keep stylists longer than a year because they're all wanting to move to the bigger city 2 hours away... someone is going to look at you and say, "so? Get a full time job here!" and basically tell you to go away.
But all is not lost... you'll probably get some help with expenses in moving back (your ex, probably not, though... it's his stupid decision to let you take his kid away from his hometown in the first place and decide to move there in the second place). OR if you want to stay, you may get some expenses paid while the divorce is pending so that you can find a job there.
There is no way they're going to say taht a relatively high earner who makes a mistake and marries a low earner is now bound to pay for her expenses for any length of time... he paid for you to live, relatively comfortably... probably in more comfort than you had before because you had to work less than half the time of yoru previous life... for a year. He'll probably have to give you a little to get back on your feet, but otehr than that, don't expect much.
There are statutes all over the place explaining that alimony can be given if there is fault, if one spouse moves for the other, etc., etc... but those are general guidelines and the judge will also consider the OTHER guidelines, like the length of the marriage and whether or not you have the opportunity to earn just as much as you were earning a year ago when you married him, if only you go back... and in a very short marriage, the considerations will probably be that he owes you just enough to get re-settled soemplace else. I know that's not what you want to hear, but that's what it probably is. Now that you know he intends to separate, your first move needs to be to either find full time employment where you are OR return to full time employment in your old place and ask him for help in moving you back.
