I agree with Dawn. Stick it out if you take off again. Did I ever mention that's how I got H home the first time? Was so ticked off, I just got in the car and drove off. When he called the first couple of times, I told him since he didn't want to be married anymore, then what I did was none of his business. Then I ignored the phone...and didn't come home for two days. Wish I'd known about DB back then, we probably wouldn't have had a second seperation.
Anyway...be careful about taking off out of the house for any length of time. In some places, that can be seen as abandonment of the house, and give him more legal footing if things really go south.
