The more I think about this the more it strikes me you should be getting some good legal advice sooner rather than later. You left thinking it would be a short week long break, now you and the kids are out of the house and possibly at a great disadvantage. A Lawyer might advise you to move back in immediately because you both have the same right to the home. If the marriage can't be saved it would be better for your son to not relocate homes, schools, friends, etc... The least amount of change for the kids is generally considered best.
