do what makes you happy...
Does your new job pay more than his current job? What about the cost of living there relative to where you are currently living? These are all things you should consider as well.
WTF is in Montana?
Have you discussed the specifics as to why your husband feels as he does and helped him to understand what taking this job would mean to you? If you've thoroughly discussed things and still can't agree, then I'm sorry that's tough.
Times are tough and unless your husband has some high-power job that it would be a big mistake to leave, he should give it a try. As for your kids, they are presumably very young (given your age). They will just go along with what the parents decide. Any kid would love to grow up in a Big Sky Country, truth be told.
Too small? Montana? Coming from Utah, you'd think they'd at least be familiar with western states.
Anyway, if you gave up going to the school you wanted for your husband's sake, maybe it's his turn to return the favor.
Why not give it a try? If you both decide you don't like it, you can always move back. Nothing is set in stone.
Long distance could bring out the best or worst. He might surprise you and rise to the challenge. As for being a car salesman, those are very transferable skills. Good sales skills will open doors for him in Montana too. He just needs to think a little outside the box.
by family do you mean kids? If not it's just a choice between your dream and your husband. Did he not know you were applyig for a position in another state? Would he be able to find work there? wwhich one is really better for you in the long run? There are many questions to conside when making your choice.
then accept the job and go. He knew of your dreams from the get go. You guys may not be compatable. It's something you might have to accept, and since your family belittles your goals, there's no reason to acknowledge their opinions. Just make sure you can actually support yourself and you know what you are walking into...because they don't want any parts of you dream so they are unlikely to help.
It's time to have a sit down and a heart-to-heart talk with your husband. As to the rest of the family, their opinion(s) shouldn't weigh in on the decision.
Well you have to love Montana to live in Montana.
How far away is it from where you live now?
