I think I stumbled upon a woman who is into me and I'm really into her but I haven't the slightest idea how to express that beyond kinda just saying it like a dumbass. We've hung out a few times and I'm going to reach out to go out with her again but I've got no idea how to express my actual feelings for her

I've never had a girlfriend. Only women I've been with have come onto me hard and I just halfheartedly played along. Last time I was really into a girl was years ago and I fucked it up because I didn't know how to express that. I really don't want to mess this one up though. How do I go about this?

Edit: thanks for the input everyone (silly answers too). Gonna ask her to go somewhere with me this weekend and be a little bit less coy
