Girl invited me over but didn’t go well

This girl and I have been talking for the past week with her being flirty and she invited me over today and we were both very excited to see each other since we have alot in common like humor and liking marvel and Harry Potter. I got to her house and an hour in we’re talking and playing games on her switch when she tells me that it’s a surprise double date and didn’t tell me because she didn’t know how I would react.

Being an introverted person when they came I immediately became shy in the last couple hours of the date and I thought the vibes were off. I wasn’t talking as much and when they said they were about to leave, she hinted to me leaving as well because I didn’t wanna overstay my welcome. I hugged her but no kiss or anything.

I could be overthinking this, but usually I mess up for first dates. I messaged her back when I got home saying I had a good time and I want to see her again, but she hasn’t responded within an hour. The romantic vibes seemed to disappear as the night went on, any advice on how I could have handled that better?
