I don't get it...

I was watching t.v the other day and there was this documentary on weddings, it kind of went through all the processes; the engagement, the planning, picking out the dress, the bachelor/ette parties, the rehersal dinner and of course the big day. A couple of things stuck out to me... I'm sorry, but no fiance of mine is going to be having a bachelor party, at least not the kind with naked girls. They claim it's there last night of freedom, but as I recall you're still technically commited. I would just hate for that to happen, say your soon to be husband hooked up with some skanky girl just because. I mean, what does that really say about them? I just want to be sure the guy I'm marrying is interested in sleeping with me, not anyone else.
That kind of leads into my second point, according to this show between 50 - 80 % (depending where you get your sources) of men cheat on their wives... UHH WHAT? That's incredibly high, even at the low point! That's half... that means you have a 1 in 2 chance to get a guy who's going to stay loyal and faithful. It all scares me just a little. I don't ever want to deal with that pain. It's too scary.
