Who’s Responsibility Is It To Bring Sunscreen?

Over the weekend my husband and I went rafting. It was extremely hot so everyone made sure to apply sunscreen before they left the house. I put sunscreen on my kids and myself. I sent a bottle of sunscreen with my kids but didn't pack a bottle for my husband and I because I figured he put sunscreen on. He didn't! Which means he is the color of a cherry tomatoes today. I feel terrible for him and wish he wouldn't have gotten burnt. He blames his sunburn on me because I didn't pack sunscreen for him. Is it my responsibility to pack sunscreen for him because I am his wife or should every man and women be responsible for packing their own sunscreen?
