i have no definite statistic or anything but i strongly believe that boys betray more than girls n love. i know some girls seem like sluts but that's only because all these girls have usually been really hurt by boys before that! Its impossible to say boys betray more... Because the general opinion is boys betray more... but the true fact is boys and girls equally betray... when girls betray most of the boys don't express it... but when boys betray... girls create it as an big issue. If boys need to be punished for betraying then Girls must too.... IF boys are need to be hanged then Girls must too....
