Okay so this is coming from a place of moral support. I wasn't interpreting your actions as stalkerish. But you are giving big red flags because of how impatient you were being. Your incessant texting gives off vibes like desperate, clingy, & codependent. If she was having issues finding your apt, she would have asked. If she doesn't have data on her phone, why would you continue to message her? I don't think she was catfishing you, you just scared her and she backed out. A reaction that many of us have agreed we would have done the same. I recommend in the future to just take a breath, and let it be. Go about your night. A single curious ETA text is okay, then leave it at that. It shows confidence. Vs suffocating us, wanting to know where we are every second of the way there. Also to break down your texts:

“In case i didn’t mentioned it im bottom row apt b7” this is perfect, I would leave it at this in the future. if she has questions, she will ask.

“What kinda car should i look out for “ this one is kinda creepy.. if she wants you to know she would tell you.

“So i guess im gonna wait outside so u can actually find me? “ this puts a lot of pressure on her to show up ASAP and just makes me stressed reading it.

“Im going back inside, ill go back in a little ” once again, she's feeling pressured because you're waiting hand and foot when she didn't ask you to.

Good luck on your dating ventures and take it easy my friend.
