Told her I enjoyed our time, she hits back with 'you got awkward once we left' overthinking this or is there something to read here?"

Quick context went out for drinks, ended up driving her home even though she was like 5 min from the spot and I had another 1h20 to get back myself. I work for my job in HER town. Made out, Got home around midnght and shot her a text that I made it back at 4:30 PM today. Here's how it went from there:. It seems she annoyed I took long to confirm I'm home. Shes going to Boston this week. Me: I got back Her: I was beginning to wonder! Me: No, the traffic isn't THAT bad. Me: Cut me some slack, I was watching the open Her: Yea.....at 10:30p? Oooohhhhh kaayyyyy Me: I enjoyed our time last night. A woman of the culture you are Her: I did too. Are you sure? You got very awkward once we left the bar
