Sounds like military life. You get to stay anywhere from 2 to 4 years at a place depending on your job. About the time you get settled in and know where everything is in the town/city you get orders to move.
Sometimes you have to think of the moves as chapters in your book of life. Every move is a different chapter and chance to start over and make new friends and do new things.
If you do decide to put your foot down you will have resentment and possibly a divorce. Your husband has high hopes and he is trying to get there to provide for you and your family. This is what he knows and the only way he can explain it to you.
Yes, there will come a day when you do not move and the big van does not show up at your front door to take your things away and you will cry. I know I did when I realized they would not be coming to my door any more.
Just sit down together with paper and pen and draw out where he is going and what you want and how the two of you will make these needs complete. How many years, how many more moves and when it will end?
Good luck.

PS I knew that if I didn't get along with a neighbor one of us would be gone soon and we could put up with the dfifferences for that year or so.
