I'm so sorry, I wish I could help. It is not fun being in a job you don't like. Maybe you both should talk about it and give it like 6 more months or something and see how it goes from there. In the meantime, put as much money (if you have any extra) aside to save up to move back if that is what you decide you need to do.

It's hard getting adjusted when you move. Your out of your comfort zone. You have to make new friends, learn new jobs. Basically your life probably feels topsey turvey. That can be very stressful.
Give it some time, you may settle down with time.
