Should I invite a girl who I thought had a crush on me a few months ago and hadn't seen in the past few months to the theater?

A few months ago I thought this girl liked me. but i wasn't sure. I'm still not sure yet. There is a theatrical event a few weeks later. Should I pay the fee and invite her to the theatre? By the way, the girl is very beautiful. But I don't know if she likes me.
a question I mentioned about that girl:
How do girls behave towards men they start to like, how do they behave around them, how do they feel?
