re: What are some Texan towns not named Fredericksburg for a couples weekend?

I’ll echo the Wimberly recommendations. Fun town for a weekend getaway, especially in the summer.

We stay at the Wimberly Inn (centrally located and has a cool little bar) and make it a focus to go hang out at the Blue Hole — headwaters of a spring fed creek that flows through the town. Afterwards, walk over to Community Pizza and Beer Garden

You also have Jacobs Well nearby, although it closed indefinitely to bacteria caused by the drought
