Zany it's only human nature. In order to have a good relationship you need to be aware of basic human nature. We always want something we don't have. As soon as we have something we get used to it, take it for granted and want something else. So even in relationship, you should never give the impression that the other personally totally owns you or 'has' you. Because as soon as she/her senses that then she/he will get used to it and take it for granted and will want to focus on other things.
