Much, you are not the only one taking care of him. He has friends, he has family. You're allowed time for yourself. And no, I don't think it's wrong if it's both. You learned your craft to help Robin but you are skilled at it and you do enjoy doing it. You enjoy cooking when it isn't for him, don't you? When you come here to do so, when you helped feed the poor? You're both allowed to have friends of your own, Much. You will always be his closest friend, but that doesn't mean the two of you can't be around others.
