Other than "you just know"
Most Helpful Guy
My personal opinion is that real love isn't just a feeling. Love is an action. More precisely is a commitment to sacrifice for another person. That sacrifice may be time, money, effort, or even your life, but it is always a sacrifice of some sort. This is why love is never selfish.
People build love up to be something almost magical that it can never be. Love is powerful not because it is an emotion, but rather because it is an action. Love is something we do, not something we feel.0
