How do you feel about cheating?

With all the Tiger Woods infidelity buzz circulating these days, the topic of cheating has come up quite a bit amongst my friends. I can't say for sure what I would do if my boyfriend ever cheated on me, but I do know that it wouldn't be pretty. I don't think I would--rather, could--give him a second chance. Sure, I'd probably forgive him one day, but I just don't think I could accept it. (Or does accepting and forgiving go hand-in-hand??) I'm 99.99999 percent sure this would never happen, but if it did, I'd just feel like my relationship with him was a lie. How do you regain that trust? A lot of couples do work through it though, and come out of it just fine--maybe even better than before--and there is something to be said for that, too.

Ironically, the movie, Unfaithful, is one of my all time favorites. I'm not sure why? Maybe it's because Diane Lane is so freakin' hot. I mean, all the sneaking around and rough sex makes for a pretty good movie--it's exciting. I'm sure a lot of women relate to Diane, too. She has a caring husband, beautiful house, cute kid--everything--yet, she still doesn't feel fulfilled.

As much as I like Diane's character in the movie, I never once feel sorry for her. Everyone is responsible for their decisions and happiness. I think infidelity happens because people just settle for certain things because...I don't know...it's easy? Like, how much could Tiger Woods truly be in love with his wife? I'm sure he married her because he wanted to settle down--or felt like he should. I will be a lonely, crazy cat lady before I marry someone I'm not over the moon for. I wouldn't settle for anything less than what I deserve--which is the best, of course.

OK, not to go off on a tangent here, but I also have a huge problem with people calling infidelity a mistake. A mistake to me is calling someone by the wrong name, not banging a skank behind your wife's back. But hey, that's just my humble opinion.

I don't want to generalize this topic too much--I'm aware that everything is circumstantial, and differs from one person to the next. Now that I've done my share of rambling, tell me: How do you feel about cheating? If someone cheated on you, could you give them a second chance?
