Maybe you could pose the question in a way that wouldn't seem like you're trying to ask if she's married/seeing someone... like when she says "we" you can ask "oh, you and your husband?" or something of that nature. But be smooth, not fumbly like me!
Hope you had a nice ride home. Have a happy weekend.
