How to make her happy?

me and my girlfriend have been arguing all day. it all started this morning when she wanted to go out for lunch but she knew I wanted to stay home from enjoy my day off. after about 45 minutes I finally gave in and we went to lunch. why would I want she can tell I wasn't really enjoying myself. so when we got back to the house you went to the bedroom to take a nap while I stayed in the living room and played my game. she believed I should have got in the bed with her until the nap. now she's mad at me because I didn't take a nap and play my game. what should I do to not make her have an attitude with me even though I'm still pissed off at her
