I don't think that this statement is true. Love is not a disease. Love is a healing balm, it is what makes us repsect each other as Kindred Spirits on this Earth for one.
I think a good example for my point is, some people fall in with other people and get hurt, then they get mad because they were in love, but that does not make love a disease, at all! Because when you get through with all that hollering and screaming about the "love" you thought you had, all you have to do is look within and look around, you will see that you have (or should have anyway) the Love of God, and the Love of Self. And that is what is going to see you through the rest of your Days, into infinity. So to restate my answer to your question, no I do not agree, at all, for the reason and example that I have stated.
