She’s dtf just don’t know what to say

Yup. Your clear to go for the soft close. Use the classic “do you like wine?” Then “come join me for a glass one day” the rest should be planning detail and schedule. I’d recommend transitioning off the app as well before setting up the date.

The key with DTF chicks is to play it coy when she gives you a bait to jump on. "Oh really"

I would have said "kinda?" or "kinda, you don't sound that confident."
