Maybe you could elaborate on that a bit?
We fall in love with all sorts of people for all sorts of reason, some, and in fact most are not good reasons. The act of loving someone is usually always complicated by our own preconceived (and media-sized) notions of what loving another human being means, but, despite that, we focus on the "act of loving" someone, and what we receive in return rather than the real gift, which is the knowledge that we are capable of truly loving another human being unconditionally and without reservation. Apply that, which is, for all you Christians out there, Jesus' "Golden Rule" as a test to all those failed romances and see how they stand up. It gives us the chance to view our concept of love (as it pertains to romantic love) in a different way.
If I love someome, I don't stop loving them because I didn't get what I want from them. To deny that reality of what we announced as "love" by saying that we no longer love that person, or that we "made a mistake" is to say that we are not capable of truly loving someone.
