Answer: The title "Love is a Fallacy", mean that love is blind and is selective about what they see.
Explanation: The word fallacy means a mistaken belief. And when you love someone, you tend to be naive. You ignore red flags and only see what you want to see and you can't imagine them otherwise. You have created a picture in your head of who they are based off of what you know by interaction and behavior, oblivious to the ugly side that they keep hidden. So when that side comes out, you push out the thought that that is them and you only focus on the good.
