Genuine Reactions
Most of the feelings or reactions are extremely genuine when you are in love compared to when you are not!

The Way you talk!
All of us know how we talk when we are in Love. All of us also know how we talk when we are actually not in love!

How We Look!
You know we don't really care how we look in front of the person we love! That is not the case with someone we are only with for physical reasons!

They Don't Care Either!
And just as we don't care how we look in front of our partner, our partner doesn't really care how we look at our worse if they are truly in love with us!

Things That Matter!
People in love mostly only care about things that matter the most! That is how it works ad that is what makes the relationship strong!
