Like Tracey said, moving itself is stressful then adding in the school issues and expenses and no wonder you feel this way. I agree also that a heart to heart w/ your husband should help. Then even if you do decide to go thru w/ buying the other house you will at least have his support and he can be there for you. I'm sure you'll make the right choice and try to remember that there really aren't "wrong" choices. If it turns out the move is a mistake then you move again if it turns out not moving is a mistake then there will be other houses and you can move then.
