I think that since you are married then you should definitely find somewhere else to stay together.
Although I don't know the reasons you are moving, I would go a step farther, and seriously reconsider moving to be near people seem not to consider you family, and seem not to want you around.
I think that your husband's parents are putting you into this situation to drive you apart, and I think that if you move there things will only get worse.
Do you want to put yourself in a situation where your husband will constantly have to choose between you and his mother?
If you live farther away, the tensions between you will be noticeable, but they may not affect your marriage.
If all of you live in the same town, it will be much more obvious when he seems to be choosing his mother over you, and even if he isn't doing that, the fact that they aren't willing to have you in their home will put stress on your marriage.
If your husband does decide to stay with his parents, I would definitely check on your visitation rights - can you visit whenever you want too, do you have to have their permission, and are they going to be trying to set him up with other women when you're not around (just kidding, trying to bring some lightness to the post)?
If you aren't allowed to visit on a reasonable basis, find somewhere to stay together, and if they say one thing, then change their minds about you visiting after he moves in then he needs to immediately move out to be with you so his parent will not negatively affect your relationship.
I hope everything works out ok for you and your husband, and you'll both be happy for a long, long time .
