Girlfriend touched me in my sleep?

Last night was out first night sleeping in the same bed together. It was around 1 am. She started touching the inside of my thigh and slowly started moving upward. i was in so much shock and discomforr I wanted to run out of my own house. This morning I couldn't even talk to her. i haven't texted her all day and I'm thinking about just breaking it off. what would you do in my situation?
