love hurts

Why is love so complicated? Why cant it be just simple and sweet.. why must it be of hurting one another, when u get hurt by the other.. revenging of each other when u are not happy of wat the other did before? if u really love someone so badly, will u ever bear to hurt them just so that they will know how you have hurt them as what they claim?? Certain things it’s best not knowing, if u knw it will be very hurting
