I've been watching a lot of movies/tv shows where people have affairs lately. It makes me sick to my stomache. I just watched Something Borrowed thinking it would be a cute romantic comedy, but what is cute and romantic about cheating on your fiance with her best friend? Yuck.
As far as I know I haven't been cheated on, but I wouldn't be surprised if my ex did. We were long distance so he'd easily be able to, and he lied about everything so he wasn't trustworthy at all.
