How long is too long n was this the right move?

I ask this one girl to go eat out but I was in the middle of asking her if she didn’t wanna go she didn’t have too but she cut me off and said let’s go! Now it’s been like 2 days since I said that n I’ve been busy till now and texted her if she was still down to go. She replied when? And I said when’s a good time for u? Then no reply it’s been a good 2 hours. is this a bad sign m I not seeing something or m I just being paranoid.
