What did I do wrong?

Today my girlfriend and I had the day off. I figured we can spend the day cuddling and watching TV. she's wanting to go out for breakfast then to the mall. I told her I just wanted to spend time alone today and watch TV with her. needless to I ended up going out for breakfast then out to the mall for another two hours. she can tell I wasn't having a good time out.. Now she's mad at me because I had an attitude about going out. once we got back to the house she is
not taking a nap. while I'm awake. she doesn't want me touching her because she's mad at me. What did I do wrong. I wanted to spend the day with her just not outside. but I gave in and gave her what she wanted. and she's still mad..
