why do we cheat on the one person we love...

WE????????

I really wish I knew the answer to that. I am going through it right now...after 16 years of marriage. If you find out, let me know. LOL

People have a major tendency to take things for granted, so when someone starts cheating on the other person, they think that the person there cheating on will always be there, so they can basically do whatever they want. Thats my theory anyways
