Careful.. don't mind read. Is it just grandma? Or lots of other family too?
What other communication skills have you developed that you can use? Is there a way to ask in an open ended way? (That doesn't put him on the defensive)
And, some times, spouses do have to work on holidays. It's possible, right? Let go of resentment. I know it is hard. That doesn't mean don't share how you feel (nervous about the drive, wanting to spend holiday with him), but let him make his own choices. You don't have to love his choice. But don't keep score or resent.
