Should she be mad at me?

today I had the day off work. so my girlfriend and I went to our local fair for a few hours. after that we went to her mom's house for swimming and dinner. Once we got back home we decided to watch a movie and cuddle. about half way through the movie I started to make a move, but when I realized nothing was gonna happen I got up and took a shower to take care of myself. once I got out I got back in the bed and tried cuddling her again and she push me away. she's mad because I took care of myself.
