Closing Out? (Seeking Women’s Advice)

So – just finished my second date with a woman that I’m interested in, but from everything it seems like she isn’t…

Our convos have flowed well (few if any awkward pauses) – in text and person. But in date two, just didn’t get the sense she’s really into it (offered to walk her to her car and she said to not worry about it), though she also sent weird other signals (after saying no to me walking her to her car, said, see you again soon.)…

Anyway, I’m old enough to go with my gut and the signals I read. Also old enough, though, to not just ghost or assume. So – I’m asking for women’s advice: what’s the best response that let’s her know I’m interested, but also honest about feeling like she’s not feeling it?

Is this a weird follow up tomorrow: “I really enjoy spending time with you – but I get the vibe this isn’t working for you. If I’m wrong, I’d love to see you again. If not, no worries – good luck going forward!”
