Ooops?

TLDR; Said something that came off creepy. Girl is a bit hesitant to hang out but still wants to. I want to recover my ground and flip the switch to make her commit and be excited to hang out. How do?

DETS: I said something that if said to the right person would not have been a big deal, but this girl didn't get the joke, so it came off as a bit creepy.

She replied, "I'm going to be straight with you. My roommate is literally begging me not to hang out with you. You're not going to try any funny business, right?"

This threw me off cause it got MY hamster spinning for a bit, wondering what I even did/said to come off that way until I realized what it was. I replied with "I'm going to be straight with you. Funny business is kinda my thing but creeper shady business isn't." (I defended myself here, but I wasn't sure how else to address that.)

She replies, "Okay, you seem like a dope enough dude so I will hesitantly say yes to hanging out with you on Saturday."

I don't like that so I flip the turn it around for fun here and say "Well how do I know YOU won't try any funny business? Now I'm all sorts of hesitant." She validates herself a bit and I learn that she hasn't met up with anyone on Tinder before, so the caution is understandable enough, I guess.

So... yes, I messed up and am still working on my text game, but she still does want to hang out. I want to let her know that if she's going to be all doubtful and suspicious of me, I'd rather not meet cause it'd be a waste of time for both of us. I'm confident enough in person, but text game is weak as shit. Especially on Tinder, which is a dumb app on it's own anyways, even though it helps kill commute time.

That was the only time I had to "validate" myself. The rest of the conversation before this was me steering it around, teasing, getting her number quickly, etc. And I'm fully aware I could meet up with other girls too (I am), but I don't see any big cons to potentially making a new connection/friend in the city at the very least, since I'm pretty new here myself.

How would you handle it / what would you say? What else could I have done better? Thanks in advance, guys.
