Here's the thing. The fact that you're not working (and raising kids) will be a concern to the adcom. It's politically incorrect for them to ever say that out loud, but privately that is what will be a big concern: if you sacrificed your career already for your husband (and to become unemployed in the process to be with him), it doesn't give them confidence that you will be career focused post-MBA. Yes, there is a bit of hypocrisy here on their part because in real life just about everyone (especially adcoms who may be a bit older) acknowledges that you need to balance personal life and career (and oftentimes in real life most of us do have to make compromises in our career for our personal lives - some just do it sooner than later), but for the purposes of the b-school application the ones who are 110% career focused (men or women) are the ones that have a big advantage.
So this will be a concern no matter which school you apply to, and it's going to be hard to explain away your circumstance. Also, it's not just adcoms that will be concerned, but post-MBA employers as well since so many of the kinds of jobs you get out of b-school require you to put your job above anything else.
On top of that, you are heavier on the experience side and your GMAT is skirting the bottom of the middle 80% for schools like Kellogg and Booth which will be long shots (i.e. it may not be worth applying at all since you're up against too many other applicants that the adcoms will prefer).
Schools like Ross, Cornell, Fuqua, and Stern are stretches: you may want to narrow that down to 1-2 schools.
Schools like Tepper, Texas, Georgetown, USC, etc. are sweet spots. These are the range of schools you should be focusing on.
And with this in mind you should also retake the GMAT and try and get a 700+ score.
