Nervous talking to a new girl?

I met this girl two Saturdays ago at the bar and got her number. Been talking to her for the last two days and it was going good but tonight she said she was walking to the bar so I said I'd meet her there. She was already on her way when she told me so it's not like we planned to meet up beforehand. Anyway I got nervous and left and when I got home I texted her "sorry for leaving so abruptly I was kind of nervous lol". She was with a couple friends so I don't know if it bothered her or not. Did I mess up?

When we were texting it was going really good but I just chickened out. She text me back and said "Lol totally understandable. There's always another day 😌"
