“What do you think is the point of relationships, especially the romantic variety? Nothing lasts, lea asdfadsf ”

What do you think is the point of relationships, especially the romantic variety? Nothing lasts, least of all human affection.nI think the route that would make me most happy would be to refuse relationships, but keep my heart open to love. So, for example, if I happen to fall in love, I won't deny it, but I also won't try to begin a relationship, or expect anything back from the person.nWhat do you think?nAnd thanks.
