Had a kiss after first date.. no text?

I met this girl through a friend a couple years ago, and we started talking a couple weeks ago. We decided to go on a movie date last night. She picked a scary movie and she wound up siting in my lap with my arms around her the entire time. I had to take her home shortly after the movie, but we exchanged a goodnight hug, and then SHE went in for a kiss on the lips.

I haven't texted her yet, but neither has she... Girls do you think she's interested or no?

Based on what happened last night I thought she was, but she hasn't made any contact with me since, so I'm not so sure if she was just looking to have fun last night.

How long would you wait to text a guy first after a date like that?
