Is This Seat Taken?

For the tumble prompt:

It was supposed to be your honeymoon.
Instead, your ex had turned out to be a scumbag, so here you were. Alone. On a cruise through beautiful scenery. Sure you'd used their ticket price to upgrade your own, so you had a luxury suite instead of a small cabin. And sure, the food was good, and there were plenty of activities.
But it felt like everywhere you looked you saw couples, and it was slowly killing you.
As you sat alone at dinner (again) you found yourself interrupted:
"Is this seat taken?"
