Why is she suddenly so cold towards me?

Yesterday, I met up with a girl and some friends for the first time in a few months. Last I saw her, we were cool and even texted a bit during the lockdown.

When I saw her yesterday, she was very brief with me. Only hi, bye, and when I asked her a question, she’d respond. Normally, she would ask me questions and engage me in conversation, but nothing. I don’t get it.

I did ask her out before the lockdown and she said she had something else to do. She didn’t exactly say no, but didn’t offer a make up time. I didn’t want to be too pushy either so I just dropped it. We still texted after so I thought things were ok.

Could it be that she doesn’t like me and doesn’t want to lead me on? I feel like I lost a good friend. I only asked her out because I thought she liked me. I rarely ask girls out and only do it when I’m sure there’s some level of interest. I’m just so confused, I’m not a bad guy.
