The best part of most people day is when then are by the side of someone they love, it is rare that we found someone who make's us feel like this make's us feel's like loved and there is no manual for that, you just start to love and once you do you don't stop doing it. You start to love when you meet the other person's demons and still feel it's worth it, when you fall in love with their laughter but also in those moments where they break down a little and just need to be hugged, when you fall in love with their brightness but also on it's dark side.
So i think that the problem is not love, the problem is people who don't fight for what they love.
