"Most words are just-- words people use." Don't even start on linguistics with a poet, kid. "It's society agreeing on a standard definition that gives it widespread use, but individual meaning is important as well. And even then there are different kinds of love, as well. Familial, like- between a father and son, t-the way I feel for you. Romantic, in being someone's boyfriend, or husband." Ideally, at least. "Platonic, between two friends. Ancient Greek philosophy actually goes into the definitions quite thoroughly, those have carried quite well through the ages."
