We have a similar situation to yours, OP. We have a business two hours away from home (seasonal), and firm plans to finally snowbird this winter. But now, DH couldn't resist buying into a business opportunity, so snow birding isn't an option for him. Timing is everything, right?
I've decided to head south in the RV anyway, and DH will join me for a week here and there. He's not overly enthused about me going solo. However, he won't be around home for several days at a time, so I'd be pretty much on my own there, too, (snow shovel in one hand, glass of wine in the other - ha!). The circumstance is what it is, and we're going to make the best of it for a handful of months. These are wonderful problems to have really, snowbirding versus a new business.
There are several right answers to the question, what should we do? Best wishes in whatever arrangement you two decide on.
