Well then I guess your definition of love is subjective as well. Then I have no pretense to take it up as objective love. Love isn't subjective as there is a certain chemistry involved and I do believe you can get it down to a science. There are certain biological things that occur, and it does not correlate with abusing another as with pedophilia regulates.
The reasons why we have specific terms for such things is for us to understand in the general sense. When someone indicates they are in love then we have to qualify it as something acceptable throughout so we can understand the premise of which their reasoning is. If being in love isn't what is accepted and understood widely throughout then there would be no need for words as everything is subjective and trivial.
