Whats the meaning of "if a bachelor, might sit an hour beyond the usual bedtime, and steal a kiss from the mountain maid at parting.”?

Hi guys. What’s the meaning of this sentence “And here the teamster, on his way to Portland market, would put up for the night; and, if a bachelor, might sit an hour beyond the usual bedtime, and steal a kiss from the mountain maid at parting.” in this paragraph? The wayfarer, with no companion but his staff, paused here to exchange a word, that the sense of loneliness might not utterly overcome him ere he could pass through the cleft of the mountain, or reach the first house in the valley. And here the teamster, on his way to Portland market, would put up for the night; and, if a bachelor, might sit an hour beyond the usual bedtime, and steal a kiss from the mountain maid at parting.
