Because apparently its to hard to end a relationship with someone. I for one am completely against cheating. I just do not understand it, if you are not happy, be honest and leave! Cheating is the stupid, hurtful way for some people to get out of having to really deal with their issues.
they are immature. They have mental problems and can't get their goals/morals straight. for a change in the relationship ( maybe it's too boring for them). Everyone has their own reason to cheat on their partner.
1. some people are really cheat full , they getting have Boyfriend or Girls Friend only for sexual things, 2. some people getting have relationship cause of make someone else jealous so it won't stay strong it i will happens by cheating at the end 3. some people thinking they're suit for each other so they get toward so fast before they get know each other better & well so in the end is "Cheating"
