Would you move to another country because your spouse wants to?

My husband of almost 30 years has been trying to convince me to move to another (English speaking) country. He's proposing putting our house on the market, putting money in the bank and leaving. I have a good job that I like and our families including two of our kids live just a couple of states away. How much does "for better or for worse" kick in for this situation? What are the limits of what I should be ethically obligated to do for this marriage that I committed to? Or what are his obligations to drop his sudden dream of leaving our native country where we have always lived for another?

EDIT:

Here are a lot more details. I'm most interested in how others think through a decision when you don't want what your spouse wants.

My husband is nervous about the future and also feels like it's best to "cash out" and have money in the bank instead of equity in the home we live in.

More info - I'm late 50s in technology on the sales side and if I give up my good job it would be very difficult to get a similar one due to ageism in the marketplace. I'm the primary breadwinner and have been for 15 years. He works hard too. We own a home in a HCOL that is almost paid off. Everyone we know who has sold lately has not been able to afford to downsize in our city. They had to move to cheaper nearby towns. Plus 3 of our parents are still around within driving distance along with 3 of our siblings and multiple nieces/nephews. One of our adult kids lives in the target country but the other two live in a few states away. I see them every couple months or more.

Also I have a serious performing arts hobby which I'm well networked in. I do think the place he wants to move would have amazing opportunities for that though. I don't have the right to work in the target country. I could try to transfer there internally with my employer but otherwise I don't know how I could work there at least until we get established. He has citizenship there but I don't (but he has only visited there once). By the way I haven't been contemplating retirement. My mother and her 2 remaining siblings all worked far into their 70s.
