Its for Avenue Q isn't it? Has to be! You know that'll run well. It'll be masses upon masses of work, rehearsals and then shows. You will absolutely consumed by it! You won't have time for your husband and kids anyway. And you're going to be uprooting them at important times in their lives scholastically. 11 and 14? Just going into High School, and about to start GCSEs? That'd be hard on both of them. I expect neither of them would like to leave their friends. And your hubby is probably thinking that he'll be absolutely on his own with two teenagers with NO family around to give him a night off once in a while, or friends to keep the kids entertained. And you will be working nonstop so its not going to be some romantic ideal trip, there just won't be time for that!
However, my husband and daughter would love to live in New York. I'd prefer California. But my husband has holidayed in NY before and loved it. DD has only been to Florida, bit went for a month with MIL to ALL the parks, so she just adores anything US.
I'm trying not to think about the dangers of the US right now. But presuming you'd have a work visa? If youre doing Avenue Q, and puppetry is involved, you may even qualify for a specialist work visa that would bring your family over as well. But would it be enough for you to be the sole earner, if need be? In case your DH can't get a work visa? Is it enough to cover rent in Manhatten? Or somewhere further out AND travel? What about schools? Many schools in New York are private - ie have to be paid for, or religious, and you have to have a proven relationship with a church of the same denomination
... it wouldn't be easy, even if they ALL agreed and were even excited about it!!
And as several others said, you can't force them! Especially not your husband. And if hes got an issue with you taking the kids... is it worth the divorce and argument over custody that might follow? Cos trust me, one look from a judge and you'll be banned from taking them out of the country, wherever you were planning on going, and even if they agreed!
I think youre right to think of it as a career altering job, for you. You DH maybe didn't worry about the audition because he didn't think you'd get it? I dont know, and that doesn't seem kind. But having touched on that world (I sew and have helped with specific specialised dresses etc for theatre productions), I know how many auditions can be involved in one part, only to lose out. Or indeed how many auditions you can go to for soooo many different roles that you think went really well, but dont even get a proper rejection letter from, just a no! If that! So perhaps that's why he didn't want to say no to America when you auditioned, whats the point in dashing your hopes when its unlikely anyway? You know. So that may have been him trying to be kind.
And I do understand why he doesn't want to up everything and move to NY also.
Do you think if you went alone, it would be with their blessing? And not like, an end to your marriage or anything? If not, why not consider doing that? Its a good compromise! You can facetime/skype/fly home to visit! Your costs in NY would be a LOT lower if it were just you too!!
My only other idea was, do you think you could convince them to go on a holiday there with you? Prices are good this time of year. Even if you went for a long weekend, it would give them a real life idea of a city they've never been to before. And might change their minds entirely!
If it doesn't, and you still want to go. I think you need to figure out if and how to do it alone.
You also need to figure out why you dont want to leave your kids with your DH?? Cos any time someone has mentioned that you've been like No!! And shut it down quickly. Well, unless hes abusive to them... what makes him looking after them (completely alone, with no support from either of your families or friends) in NY when youre busy 24/7 better than him looking after them (also alone, but with access to family and friends) in the UK.
The only difference is you being a bit closer if there's an emergency... But youre not going to be available to them as you are now, in either situation.
